| 29 | |
| 30 | |
| 31 Beta Release 0.1.18 (2 September, 2011) | |
| 32 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
| 33 | |
| 34 Notable changes in samtools: | |
| 35 | |
| 36 * Support the new =/X CIGAR operators (by Peter Cock). | |
| 37 | |
| 38 * Allow to subsample BAM while keeping the pairing intact (view -s). | |

| 53 | |
| 54 (0.1.18: 2 September 2011, r982:295) | |
| 55 | |
| 56 | |
| 57 | |
| 58 Beta Release 0.1.17 (6 July, 2011) | |
| 59 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
| 60 | |
| 61 With the maturity of `mpileup' and the lack of update in the `pileup' command, | |
| 62 the `pileup' command is now formally dropped. Most of the pileup functionality, | |
| 63 such as outputting mapping quality and read positions, have been added | |
| 64 `mpileup'. | |
| 65 | |
| 66 Since this release, `bcftools view' is able to perform contrast SNP calling | |
| 67 (option -T) for discovering de novo and/or somatic mutations between a pair of | |
| 68 samples or in a family trio. Potential mutations are scored by a log likelihood | |
| 69 ratio, which is very simple in math, but should be comparable to more | |
| 70 sophisticated methods. Note that getting the score is only the very first step. | |
| 71 A lot more need to be done to reduce systematical errors due to mapping and | |
| 72 reference errors and structural variations. | |
| 73 | |
| 74 Other notable changes in samtools: | |
| 75 | |
| 76 * Improved sorting order checking during indexing. | |
| 77 | |
| 78 * Improved region parsing. Colons in reference sequence names are parsed | |
| 79 properly. | |
| 80 | |
| 81 * Fixed an issue where mpileup does not apply BAQ for the first few reads when | |
| 82 a region is specified. | |
| 83 | |
| 84 * Fixed an issue where `faidx' does not work with FASTA files with long lines. | |
| 85 | |
| 86 * Bugfix: wrong SP genotype information in the BCF output. | |
| 87 | |
| 88 Other notable changes in bcftools: | |
| 89 | |
| 90 * Output the ML esitmate of the allele count. | |
| 91 | |
| 92 * Added the HWE plus F<0 filter to varFilter. For multiple samples, it | |
| 93 effectively filters false heterozygous calls around centromeres. | |
| 94 | |
| 95 * For association mapping, perform both 1-degree and 2-degree test. The | |
| 96 2-degree test is conservative but more robust to HWE violation. | |
| 97 | |
| 98 (0.1.17: 6 July 2011, r973:277) | |
| 99 | |
| 100 | |
| 101 | |
| 102 Beta Release 0.1.16 (21 April, 2011) | |
| 103 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
| 104 | |
| 105 Notable changes in samtools: | |
| 106 | |
| 107 * Support the new SAM/BAM type `B' in the latest SAM spec v1.4. | |
| 108 | |
| 109 * When the output file of `samtools merge' exists, do not overwrite it unless | |
| 110 a new command-line option `-f' is applied. | |
| 111 | |
| 112 * Bugfix: BED support is not working when the input BED is not sorted. | |
| 113 | |
| 114 * Bugfix: some reads without coordinates but given on the reverse strand are | |
| 115 lost in merging. | |
| 116 | |
| 117 Notable changes in bcftools: | |
| 118 | |
| 119 * Code cleanup: separated max-likelihood inference and Bayesian inference. | |
| 120 | |
| 121 * Test Hardy-Weinberg equilibrium with a likelihood-ratio test. | |
| 122 | |
| 123 * Provided another association test P-value by likelihood-ratio test. | |
| 124 | |
| 125 * Use Brent's method to estimate the site allele frequency when EM converges | |
| 126 slowly. The resulting ML estimate of allele frequnecy is more accurate. | |
| 127 | |
| 128 * Added the `ldpair' command, which computes r^2 between SNP pairs given in | |
| 129 an input file. | |
| 130 | |
| 131 Also, the `pileup' command, which has been deprecated by `mpileup' since | |
| 132 version 0.1.10, will be dropped in the next release. The old `pileup' command | |
| 133 is substandard and causing a lot of confusion. | |
| 134 | |
| 135 (0.1.16: 21 April 2011, r963:234) | |
| 136 | |
| 137 | |
| 138 | |
| 139 Beta Release 0.1.15 (10 April, 2011) | |
| 140 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
| 141 | |
| 142 Noteable changes: | |
| 143 | |
| 144 * Allow to perform variant calling or to extract information in multiple | |
| 145 regions specified by a BED file (`samtools mpileup -l', `samtools view -L' | |
| 146 and `bcftools view -l'). | |
| 147 | |
| 148 * Added the `depth' command to samtools to compute the per-base depth with a | |
| 149 simpler interface. File `bam2depth.c', which implements this command, is the | |
| 150 recommended example on how to use the mpileup APIs. | |
| 151 | |
| 152 * Estimate genotype frequencies with ML; perform chi^2 based Hardy-Weinberg | |
| 153 test using this estimate. | |
| 154 | |
| 155 * For `samtools view', when `-R' is specified, drop read groups in the header | |
| 156 that are not contained in the specified file. | |
| 157 | |
| 158 * For `samtools flagstat', separate QC-pass and QC-fail reads. | |
| 159 | |
| 160 * Improved the command line help of `samtools mpileup' and `bcftools view'. | |
| 161 | |
| 162 * Use a global variable to control the verbose level of samtools stderr | |
| 163 output. Nonetheless, it has not been full utilized. | |
| 164 | |
| 165 * Fixed an issue in association test which may report false associations, | |
| 166 possibly due to floating point underflow. | |
| 167 | |
| 168 (0.1.15: 10 April 2011, r949:203) | |
| 169 | |
| 170 | |
| 171 | |
| 172 Beta release 0.1.14 (21 March, 2011) | |
| 173 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
| 174 | |
| 175 This release implements a method for testing associations for case-control | |
| 176 data. The method does not call genotypes but instead sums over all genotype | |
| 177 configurations to compute a chi^2 based test statistics. It can be potentially | |
| 178 applied to comparing a pair of samples (e.g. a tumor-normal pair), but this | |
| 179 has not been evaluated on real data. | |
| 180 | |
| 181 Another new feature is to make X chromosome variant calls when female and male | |
| 182 samples are both present. The user needs to provide a file indicating the | |
| 183 ploidy of each sample (see also manual bcftools/bcftools.1). | |
| 184 | |
| 185 Other notable changes: | |
| 186 | |
| 187 * Added `bcftools view -F' to parse BCF files generated by samtools r921 or | |
| 188 older which encodes PL in a different way. | |
| 189 | |
| 190 * Changed the behavior of `bcftools view -s'. Now when a list of samples is | |
| 191 provided, the samples in the output will be reordered to match the ordering | |
| 192 in the sample list. This change is mainly designed for association test. | |
| 193 | |
| 194 * Sped up `bcftools view -v' for target sequencing given thousands of samples. | |
| 195 Also added a new option `view -d' to skip loci where only a few samples are | |
| 196 covered by reads. | |
| 197 | |
| 198 * Dropped HWE test. This feature has never been implemented properly. An EM | |
| 199 should be much better. To be implemented in future. | |
| 200 | |
| 201 * Added the `cat' command to samtools. This command concatenate BAMs with | |
| 202 identical sequence dictionaries in an efficient way. Modified from bam_cat.c | |
| 203 written by Chris Saunders. | |
| 204 | |
| 205 * Added `samtools view -1' to write BAMs at a low compression level but twice | |
| 206 faster to create. The `sort' command generates temporary files at a low | |
| 207 compression level as well. | |
| 208 | |
| 209 * Added `samtools mpileup -6' to accept "BAM" with Illumina 1.3+ quality | |
| 210 strings (strictly speaking, such a file is not BAM). | |
| 211 | |
| 212 * Added `samtools mpileup -L' to skip INDEL calling in regions with | |
| 213 excessively high coverage. Such regions dramatically slow down mpileup. | |
| 214 | |
| 215 * Updated `misc/export2sam.pl', provided by Chris Saunders from Illumina Inc. | |
| 216 | |
| 217 (0.1.14: 21 March 2011, r933:170) | |
| 218 | |
| 219 | |
| 220 | |
| 221 Beta release 0.1.13 (1 March, 2011) | |
| 222 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
| 223 | |
| 224 The most important though largely invisible modification is the change of the | |
| 225 order of genotypes in the PL VCF/BCF tag. This is to conform the upcoming VCF | |
| 226 spec v4.1. The change means that 0.1.13 is not backward compatible with VCF/BCF | |
| 227 generated by samtools older than r921 inclusive. VCF/BCF generated by the new | |
| 228 samtools will contain a line `##fileformat=VCFv4.1' as well as the samtools | |
| 229 version number. | |
| 230 | |
| 231 Single Individual Haplotyping (SIH) is added as an experimental feature. It | |
| 232 originally aims to produce haploid consensus from fosmid pool sequencing, but | |
| 233 also works with short-read data. For short reads, phased blocks are usually too | |
| 234 short to be useful in many applications, but they can help to rule out part of | |
| 235 SNPs close to INDELs or between copies of CNVs. | |
| 236 | |
| 237 | |
| 238 Other notable changes in samtools: | |
| 239 | |
| 240 * Construct per-sample consensus to reduce the effect of nearby SNPs in INDEL | |
| 241 calling. This reduces the power but improves specificity. | |
| 242 | |
| 243 * Improved sorting order checking in indexing. Now indexing is the preferred way | |
| 244 to check if a BAM is sorted. | |
| 245 | |
| 246 * Added a switch `-E' to mpileup and calmd. This option uses an alternative way | |
| 247 to apply BAQ, which increases sensistivity, especially to MNPs, at the cost of | |
| 248 a little loss in specificity. | |
| 249 | |
| 250 * Added `mpileup -A' to allow to use reads in anomalous pairs in SNP calling. | |
| 251 | |
| 252 * Added `mpileup -m' to allow fine control of the collection of INDEL candidates. | |
| 253 | |
| 254 * Added `mpileup -S' to compute per-sample strand bias P-value. | |
| 255 | |
| 256 * Added `mpileup -G' to exclude read groups in variant calling. | |
| 257 | |
| 258 * Fixed segfault in indel calling related to unmapped and refskip reads. | |
| 259 | |
| 260 * Fixed an integer overflow in INDEL calling. This bug produces wrong INDEL | |
| 261 genotypes for longer short INDELs, typically over 10bp. | |
| 262 | |
| 263 * Fixed a bug in tview on big-endian machines. | |
| 264 | |
| 265 * Fixed a very rare memory issue in bam_md.c | |
| 266 | |
| 267 * Fixed an out-of-boundary bug in mpileup when the read base is `N'. | |
| 268 | |
| 269 * Fixed a compiling error when the knetfile library is not used. Fixed a | |
| 270 library compiling error due to the lack of bam_nt16_nt4_table[] table. | |
| 271 Suppress a compiling warning related to the latest zlib. | |
| 272 | |
| 273 | |
| 274 Other notable changes in bcftools: | |
| 275 | |
| 276 * Updated the BCF spec. | |
| 277 | |
| 278 * Added the `FQ' VCF INFO field, which gives the phred-scaled probability | |
| 279 of all samples being the same (identical to the reference or all homozygous | |
| 280 variants). Option `view -f' has been dropped. | |
| 281 | |
| 282 * Implementated of "vcfutils.pl vcf2fq" to generate a consensus sequence | |
| 283 similar to "samtools.pl pileup2fq". | |
| 284 | |
| 285 * Make sure the GT FORMAT field is always the first FORMAT to conform the VCF | |
| 286 spec. Drop bcf-fix.pl. | |
| 287 | |
| 288 * Output bcftools specific INFO and FORMAT in the VCF header. | |
| 289 | |
| 290 * Added `view -s' to call variants from a subset of samples. | |
| 291 | |
| 292 * Properly convert VCF to BCF with a user provided sequence dictionary. Nonetheless, | |
| 293 custom fields are still unparsed and will be stored as a missing value. | |
| 294 | |
| 295 * Fixed a minor bug in Fisher's exact test; the results are rarely changed. | |
| 296 | |
| 297 | |
| 298 (0.1.13: 1 March 2011, r926:134) | |
| 299 | |
| 300 | |
| 301 | |
| 302 Beta release 0.1.12a (2 December, 2010) | |
| 303 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
| 304 | |
| 305 This is another bug fix release: | |
| 306 | |
| 307 * Fixed a memory violation in mpileup, which causes segfault. Release | |
| 308 0.1.9 and above are affected. | |
| 309 | |
| 310 * Fixed a memory violation in the indel caller, which does not causes | |
| 311 segfault, but may potentially affect deletion calls in an unexpected | |
| 312 way. Release 0.1.10 and above are affected. | |
| 313 | |
| 314 * Fixed a bug in computing r-square in bcftools. Few are using this | |
| 315 functionality and it only has minor effect. | |
| 316 | |
| 317 * Fixed a memory leak in bam_fetch(). | |
| 318 | |
| 319 * Fixed a bug in writing meta information to the BAM index for the last | |
| 320 sequence. This bug is invisible to most users, but it is a bug anyway. | |
| 321 | |
| 322 * Fixed a bug in bcftools which causes false "DP4=0,0,0,0" annotations. | |
| 323 | |
| 324 (0.1.12: 2 December 2010, r862) | |
| 325 | |
| 326 | |
| 327 | |
| 328 Beta release 0.1.11 (21 November, 2010) | |
| 329 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
| 330 | |
| 331 This is mainly a bug fix release: | |
| 332 | |
| 333 * Fixed a bug in random retrieval (since 0.1.8). It occurs when reads | |
| 334 are retrieved from a small region containing no reads. | |
| 335 | |
| 336 * Fixed a bug in pileup (since 0.1.9). The bug causes an assertion | |
| 337 failure when the first CIGAR operation is a deletion. | |
| 338 | |
| 339 * Improved fault tolerence in remote access. | |
| 340 | |
| 341 One minor feature has been implemented in bcftools: | |
| 342 | |
| 343 * Added a reference-free variant calling mode. In this mode, a site is | |
| 344 regarded as a variat iff the sample(s) contains two or more alleles; | |
| 345 the meaning of the QUAL field in the VCF output is changed | |
| 346 accordingly. Effectively, the reference allele is irrelevant to the | |
| 347 result in the new mode, although the reference sequence has to be | |
| 348 used in realignment when SAMtools computes genotype likelihoods. | |
| 349 | |
| 350 In addition, since 0.1.10, the `pileup' command has been deprecated by | |
| 351 `mpileup' which is more powerful and more accurate. The `pileup' command | |
| 352 will not be removed in the next few releases, but new features will not | |
| 353 be added. | |
| 354 | |
| 355 (0.1.11: 21 November 2010, r851) | |
| 356 | |
| 357 | |
| 358 | |
| 359 Beta Release 0.1.10 (16 November, 2010) | |
| 360 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
| 361 | |
| 362 This release is featured as the first major improvement to the indel | |
| 363 caller. The method is similar to the old one implemented in the pileup | |
| 364 command, but the details are handled more carefully both in theory and | |
| 365 in practice. As a result, the new indel caller usually gives more | |
| 366 accurate indel calls, though at the cost of sensitivity. The caller is | |
| 367 implemented in the mpileup command and is invoked by default. It works | |
| 368 with multiple samples. | |
| 369 | |
| 370 Other notable changes: | |
| 371 | |
| 372 * With the -r option, the calmd command writes the difference between | |
| 373 the original base quality and the BAQ capped base quality at the BQ | |
| 374 tag but does not modify the base quality. Please use -Ar to overwrite | |
| 375 the original base quality (the 0.1.9 behavior). | |
| 376 | |
| 377 * Allow to set a maximum per-sample read depth to reduce memory. In | |
| 378 0.1.9, most of memory is wasted for the ultra high read depth in some | |
| 379 regions (e.g. the chr1 centromere). | |
| 380 | |
| 381 * Optionally write per-sample read depth and per-sample strand bias | |
| 382 P-value. | |
| 383 | |
| 384 * Compute equal-tail (Bayesian) credible interval of site allele | |
| 385 frequency at the CI95 VCF annotation. | |
| 386 | |
| 387 * Merged the vcfutils.pl varFilter and filter4vcf for better SNP/indel | |
| 388 filtering. | |
| 389 | |
| 390 (0.1.10: 16 November 2010, r829) | |
| 391 | |
| 392 | |
| 393 | |
| 394 Beta Release 0.1.9 (27 October, 2010) | |
| 395 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
| 396 | |
| 397 This release is featured as the first major improvement to the samtools' | |
| 398 SNP caller. It comes with a revised MAQ error model, the support of | |
| 399 multi-sample SNP calling and the computation of base alignment quality | |
| 400 (BAQ). | |
| 401 | |
| 402 The revised MAQ error model is based on the original model. It solves an | |
| 403 issue of miscalling SNPs in repetitive regions. Althought such SNPs can | |
| 404 usually be filtered at a later step, they mess up unfiltered calls. This | |
| 405 is a theoretical flaw in the original model. The revised MAQ model | |
| 406 deprecates the orginal MAQ model and the simplified SOAPsnp model. | |
| 407 | |
| 408 Multi-sample SNP calling is separated in two steps. The first is done by | |
| 409 samtools mpileup and the second by a new program, bcftools, which is | |
| 410 included in the samtools source code tree. Multi-sample SNP calling also | |
| 411 works for single sample and has the advantage of enabling more powerful | |
| 412 filtration. It is likely to deprecate pileup in future once a proper | |
| 413 indel calling method is implemented. | |
| 414 | |
| 415 BAQ is the Phred-scaled probability of a read base being wrongly | |
| 416 aligned. Capping base quality by BAQ has been shown to be very effective | |
| 417 in suppressing false SNPs caused by misalignments around indels or in | |
| 418 low-complexity regions with acceptable compromise on computation | |
| 419 time. This strategy is highly recommended and can be used with other SNP | |
| 420 callers as well. | |
| 421 | |
| 422 In addition to the three major improvements, other notable changes are: | |
| 423 | |
| 424 * Changes to the pileup format. A reference skip (the N CIGAR operator) | |
| 425 is shown as '<' or '>' depending on the strand. Tview is also changed | |
| 426 accordingly. | |
| 427 | |
| 428 * Accelerated pileup. The plain pileup is about 50% faster. | |
| 429 | |
| 430 * Regional merge. The merge command now accepts a new option to merge | |
| 431 files in a specified region. | |
| 432 | |
| 433 * Fixed a bug in bgzip and razip which causes source files to be | |
| 434 deleted even if option -c is applied. | |
| 435 | |
| 436 * In APIs, propogate errors to downstream callers and make samtools | |
| 437 return non-zero values once errors occur. | |
| 438 | |
| 439 (0.1.9: 27 October 2010, r783) | |
| 440 | |
| 441 | |
| 442 | |
| 443 Beta Release 0.1.8 (11 July, 2010) | |
| 444 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
| 445 | |
| 446 Notable functional changes: | |
| 447 | |
| 448 * Added the `reheader' command which replaces a BAM header with a new | |
| 449 header. This command is much faster than replacing header by | |
| 450 BAM->SAM->BAM conversions. | |
| 451 | |
| 452 * Added the `mpileup' command which computes the pileup of multiple | |
| 453 alignments. | |
| 454 | |
| 455 * The `index' command now stores the number of mapped and unmapped | |
| 456 reads in the index file. This information can be retrieved quickly by | |
| 457 the new `idxstats' command. | |
| 458 | |
| 459 * By default, pileup used the SOAPsnp model for SNP calling. This | |
| 460 avoids the floating overflow in the MAQ model which leads to spurious | |
| 461 calls in repetitive regions, although these calls will be immediately | |
| 462 filtered by varFilter. | |
| 463 | |
| 464 * The `tview' command now correctly handles CIGARs like 7I10M and | |
| 465 10M1P1I10M which cause assertion failure in earlier versions. | |
| 466 | |
| 467 * Tview accepts a region like `=10,000' where `=' stands for the | |
| 468 current sequence name. This saves typing for long sequence names. | |
| 469 | |
| 470 * Added the `-d' option to `pileup' which avoids slow indel calling | |
| 471 in ultradeep regions by subsampling reads locally. | |
| 472 | |
| 473 * Added the `-R' option to `view' which retrieves alignments in read | |
| 474 groups listed in the specified file. | |
| 475 | |
| 476 Performance improvements: | |
| 477 | |
| 478 * The BAM->SAM conversion is up to twice faster, depending on the | |
| 479 characteristic of the input. | |
| 480 | |
| 481 * Parsing SAM headers with a lot of reference sequences is now much | |
| 482 faster. | |
| 483 | |
| 484 * The number of lseek() calls per query is reduced when the query | |
| 485 region contains no read alignments. | |
| 486 | |
| 487 Bug fixes: | |
| 488 | |
| 489 * Fixed an issue in the indel caller that leads to miscall of indels. | |
| 490 Note that this solution may not work well when the sequencing indel | |
| 491 error rate is higher than the rate of SNPs. | |
| 492 | |
| 493 * Fixed another issue in the indel caller which may lead to incorrect | |
| 494 genotype. | |
| 495 | |
| 496 * Fixed a bug in `sort' when option `-o' is applied. | |
| 497 | |
| 498 * Fixed a bug in `view -r'. | |
| 499 | |
| 500 APIs and other changes: | |
| 501 | |
| 502 * Added iterator interfaces to random access and pileup. The callback | |
| 503 interfaces directly call the iterator interfaces. | |
| 504 | |
| 505 * The BGZF blocks holding the BAM header are indepedent of alignment | |
| 506 BGZF blocks. Alignment records shorter than 64kB is guaranteed to be | |
| 507 fully contained in one BGZF block. This change is fully compatible | |
| 508 with the old version of samtools/picard. | |
| 509 | |
| 510 Changes in other utilities: | |
| 511 | |
| 512 * Updated export2sam.pl by Chris Saunders. | |
| 513 | |
| 514 * Improved the sam2vcf.pl script. | |
| 515 | |
| 516 * Added a Python version of varfilter.py by Aylwyn Scally. | |
| 517 | |
| 518 (0.1.8: 11 July 2010, r613) | |
| 519 | |
| 520 | |
| 521 | |
| 522 Beta Release 0.1.7 (10 November, 2009) | |
| 523 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
| 524 | |
| 525 Notable changes: | |
| 526 | |
| 527 * Improved the indel caller in complex scenariors, in particular for | |
| 528 long reads. The indel caller is now able to make reasonable indel | |
| 529 calls from Craig Venter capillary reads. | |
| 530 | |
| 531 * Rewrote single-end duplicate removal with improved | |
| 532 performance. Paired-end reads are not touched. | |
| 533 | |
| 534 * Duplicate removal is now library aware. Samtools remove potential | |
| 535 PCR/optical dupliates inside a library rather than across libraries. | |
| 536 | |
| 537 * SAM header is now fully parsed, although this functionality is not | |
| 538 used in merging and so on. | |
| 539 | |
| 540 * In samtools merge, optionally take the input file name as RG-ID and | |
| 541 attach the RG tag to each alignment. | |
| 542 | |
| 543 * Added FTP support in the RAZF library. RAZF-compressed reference | |
| 544 sequence can be retrieved remotely. | |
| 545 | |
| 546 * Improved network support for Win32. | |
| 547 | |
| 548 * Samtools sort and merge are now stable. | |
| 549 | |
| 550 Changes in other utilities: | |
| 551 | |
| 552 * Implemented sam2vcf.pl that converts the pileup format to the VCF | |
| 553 format. | |
| 554 | |
| 555 * This release of samtools is known to work with the latest | |
| 556 Bio-Samtools Perl module. | |
| 557 | |
| 558 (0.1.7: 10 November 2009, r510) | |
| 559 | |
| 560 | |
| 561 | |
| 562 Beta Release 0.1.6 (2 September, 2009) | |
| 563 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
| 564 | |
| 565 Notable changes: | |
| 566 | |
| 567 * In tview, do not show a blank screen when no reads mapped to the | |
| 568 corresponding region. | |
| 569 | |
| 570 * Implemented native HTTP support in the BGZF library. Samtools is now | |
| 571 able to directly open a BAM file on HTTP. HTTP proxy is also | |
| 572 supported via the "http_proxy" environmental variable. | |
| 573 | |
| 574 * Samtools is now compitable with the MinGW (win32) compiler and the | |
| 575 PDCurses library. | |
| 576 | |
| 577 * The calmd (or fillmd) command now calculates the NM tag and replaces | |
| 578 MD tags if they are wrong. | |
| 579 | |
| 580 * The view command now recognizes and optionally prints FLAG in HEXs or | |
| 581 strings to make a SAM file more friendly to human eyes. This is a | |
| 582 samtools-C extension, not implemented in Picard for the time | |
| 583 being. Please type `samtools view -?' for more information. | |
| 584 | |
| 585 * BAM files now have an end-of-file (EOF) marker to facilitate | |
| 586 truncation detection. A warning will be given if an on-disk BAM file | |
| 587 does not have this marker. The warning will be seen on BAM files | |
| 588 generated by an older version of samtools. It does NO harm. | |
| 589 | |
| 590 * New key bindings in tview: `r' to show read names and `s' to show | |
| 591 reference skip (N operation) as deletions. | |
| 592 | |
| 593 * Fixed a bug in `samtools merge -n'. | |
| 594 | |
| 595 * Samtools merge now optionally copies the header of a user specified | |
| 596 SAM file to the resultant BAM output. | |
| 597 | |
| 598 * Samtools pileup/tview works with a CIGAR with the first or the last | |
| 599 operation is an indel. | |
| 600 | |
| 601 * Fixed a bug in bam_aux_get(). | |
| 602 | |
| 603 | |
| 604 Changes in other utilies: | |
| 605 | |
| 606 * Fixed wrong FLAG in maq2sam. | |
| 607 | |
| 608 | |
| 609 (0.1.6: 2 September 2009, r453) | |
| 610 | |
| 611 | |
| 612 | |
| 613 Beta Release 0.1.5 (7 July, 2009) | |
| 614 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
| 615 | |
| 616 Notable changes: | |
| 617 | |
| 618 * Support opening a BAM alignment on FTP. Users can now use "tview" to | |
| 619 view alignments at the NCBI ftp site. Please read manual for more | |
| 620 information. | |
| 621 | |
| 622 * In library, propagate errors rather than exit or complain assertion | |
| 623 failure. | |
| 624 | |
| 625 * Simplified the building system and fixed compiling errors caused by | |
| 626 zlib<1.2.2.1. | |
| 627 | |
| 628 * Fixed an issue about lost header information when a SAM is imported | |
| 629 with "view -t". | |
| 630 | |
| 631 * Implemented "samtool.pl varFilter" which filters both SNPs and short | |
| 632 indels. This command replaces "indelFilter". | |
| 633 | |
| 634 * Implemented "samtools.pl pileup2fq" to generate FASTQ consensus from | |
| 635 pileup output. | |
| 636 | |
| 637 * In pileup, cap mapping quality at 60. This helps filtering when | |
| 638 different aligners are in use. | |
| 639 | |
| 640 * In pileup, allow to output variant sites only. | |
| 641 | |
| 642 * Made pileup generate correct calls in repetitive region. At the same | |
| 643 time, I am considering to implement a simplified model in SOAPsnp, | |
| 644 although this has not happened yet. | |
| 645 | |
| 646 * In view, added '-u' option to output BAM without compression. This | |
| 647 option is preferred when the output is piped to other commands. | |
| 648 | |
| 649 * In view, added '-l' and '-r' to get the alignments for one library or | |
| 650 read group. The "@RG" header lines are now partially parsed. | |
| 651 | |
| 652 * Do not include command line utilities to libbam.a. | |
| 653 | |
| 654 * Fixed memory leaks in pileup and bam_view1(). | |
| 655 | |
| 656 * Made faidx more tolerant to empty lines right before or after FASTA > | |
| 657 lines. | |
| 658 | |
| 659 | |
| 660 Changes in other utilities: | |
| 661 | |
| 662 * Updated novo2sam.pl by Colin Hercus, the key developer of novoalign. | |
| 663 | |
| 664 | |
| 665 This release involves several modifications to the key code base which | |
| 666 may potentially introduce new bugs even though we have tried to minimize | |
| 667 this by testing on several examples. Please let us know if you catch | |
| 668 bugs. | |
| 669 | |
| 670 (0.1.5: 7 July 2009, r373) | |
| 671 | |
| 672 | |
| 673 | |
| 674 Beta Release 0.1.4 (21 May, 2009) | |
| 675 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
| 676 | |
| 677 Notable changes: | |
| 678 | |
| 679 * Added the 'rmdupse' command: removing duplicates for SE reads. | |
| 680 | |
| 681 * Fixed a critical bug in the indel caller: clipped alignments are not | |
| 682 processed correctly. | |
| 683 | |
| 684 * Fixed a bug in the tview: gapped alignment may be incorrectly | |
| 685 displayed. | |
| 686 | |
| 687 * Unified the interface to BAM and SAM I/O. This is done by | |
| 688 implementing a wrapper on top of the old APIs and therefore old APIs | |
| 689 are still valid. The new I/O APIs also recognize the @SQ header | |
| 690 lines. | |
| 691 | |
| 692 * Generate the MD tag. | |
| 693 | |
| 694 * Generate "=" bases. However, the indel caller will not work when "=" | |
| 695 bases are present. | |
| 696 | |
| 697 * Enhanced support of color-read display (by Nils Homer). | |
| 698 | |
| 699 * Implemented the GNU building system. However, currently the building | |
| 700 system does not generate libbam.a. We will improve this later. For | |
| 701 the time being, `make -f Makefile.generic' is preferred. | |
| 702 | |
| 703 * Fixed a minor bug in pileup: the first read in a chromosome may be | |
| 704 skipped. | |
| 705 | |
| 706 * Fixed bugs in bam_aux.c. These bugs do not affect other components as | |
| 707 they were not used previously. | |
| 708 | |
| 709 * Output the 'SM' tag from maq2sam. | |
| 710 | |
| 711 (0.1.4: 21 May 2009, r297) | |
| 712 | |
| 713 | |
| 714 | |
| 715 Beta Release 0.1.3 (15 April, 2009) | |
| 716 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
| 717 | |
| 718 Notable changes in SAMtools: | |
| 719 | |
| 720 * SAMtools is more consistent with the specification: a) '*' in the | |
| 721 QUAL field is allowed; b) the field separator is TAB only and SPACE | |
| 722 is treated as a character in a field; c) empty header is allowed. | |
| 723 | |
| 724 * Implemented GLFv3 support in pileup. | |
| 725 | |
| 726 * Fixed a severe bug in fixmate: strand information is wrongly | |
| 727 overwritten. | |
| 728 | |
| 729 * Fixed a bug in alignment retrieval: alignments bridging n*16384bp are | |
| 730 not correctly retrieved sometimes. | |
| 731 | |
| 732 * Fixed a bug in rmdup: segfault if unmapped reads are present. | |
| 733 | |
| 734 * Move indel_filter.pl to samtools.pl and improved the filtering by | |
| 735 checking the actual number of alignments containing indels. The indel | |
| 736 pileup line is also changed a little to make this filtration easier. | |
| 737 | |
| 738 * Fixed a minor bug in indexing: the bin number of an unmapped read is | |
| 739 wrongly calculated. | |
| 740 | |
| 741 * Added `flagstat' command to show statistics on the FLAG field. | |
| 742 | |
| 743 * Improved indel caller by setting the maximum window size in local | |
| 744 realignment. | |
| 745 | |
| 746 Changes in other utilities: | |
| 747 | |
| 748 * Fixed a bug in maq2sam: a tag name is obsolete. | |
| 749 | |
| 750 * Improvement to wgsim: a) added support for SOLiD read simulation; b) | |
| 751 show the number of substitutions/indels/errors in read name; c) | |
| 752 considerable code clean up. | |
| 753 | |
| 754 * Various converters: improved functionality in general. | |
| 755 | |
| 756 * Updated the example SAM due to the previous bug in fixmate. | |
| 757 | |
| 758 (0.1.3: 15 April 2009, r227) | |
| 759 | |
| 760 | |
| 761 | |
| 762 Beta Release 0.1.2 (28 January, 2008) | |
| 763 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
| 764 | |
| 765 Notable changes in SAMtools: | |
| 766 | |
| 767 * Implemented a Bayesian indel caller. The new caller generate scores | |
| 768 and genotype and is potentially more accurate than Maq's indel | |
| 769 caller. The pileup format is also changed accordingly. | |
| 770 | |
| 771 * Implemented rmdup command: remove potential PCR duplicates. Note that | |
| 772 this command ONLY works for FR orientation and requires ISIZE is | |
| 773 correctly set. | |
| 774 | |
| 775 * Added fixmate command: fill in mate coordinates, ISIZE and mate | |
| 776 related flags from a name-sorted alignment. | |
| 777 | |
| 778 * Fixed a bug in indexing: reads bridging 16x kbp were not retrieved. | |
| 779 | |
| 780 * Allow to select reads shown in the pileup output with a mask. | |
| 781 | |
| 782 * Generate GLFv2 from pileup. | |
| 783 | |
| 784 * Added two more flags for flagging PCR/optical duplicates and for QC | |
| 785 failure. | |
| 786 | |
| 787 * Fixed a bug in sort command: name sorting for large alignment did not | |
| 788 work. | |
| 789 | |
| 790 * Allow to completely disable RAZF (using Makefile.lite) as some people | |
| 791 have problem to compile it. | |
| 792 | |
| 793 * Fixed a bug in import command when there are reads without | |
| 794 coordinates. | |
| 795 | |
| 796 * Fixed a bug in tview: clipping broke the alignment viewer. | |
| 797 | |
| 798 * Fixed a compiling error when _NO_CURSES is applied. | |
| 799 | |
| 800 * Fixed a bug in merge command. | |
| 801 | |
| 802 Changes in other utilities: | |
| 803 | |
| 804 * Added wgsim, a paired-end reads simulator. Wgsim was adapted from | |
| 805 maq's reads simulator. Colin Hercus further improved it to allow | |
| 806 longer indels. | |
| 807 | |
| 808 * Added wgsim_eval.pl, a script that evaluates the accuracy of | |
| 809 alignment on reads generated by wgsim. | |
| 810 | |
| 811 * Added soap2sam.pl, a SOAP2->SAM converter. This converter does not | |
| 812 work properly when multiple hits are output. | |
| 813 | |
| 814 * Added bowtie2sam.pl, a Bowtie->SAM converter. Only the top hit will | |
| 815 be retained when multiple hits are present. | |
| 816 | |
| 817 * Fixed a bug in export2sam.pl for QC reads. | |
| 818 | |
| 819 * Support RG tag at MAQ->SAM converter. | |
| 820 | |
| 821 * Added novo2sam.pl, a NovoAlign->SAM converter. Multiple hits and | |
| 822 indel are not properly handled, though. | |
| 823 | |
| 824 * Added zoom2sam.pl, a ZOOM->SAM converter. It only works with the | |
| 825 default Illumina output. | |
| 826 | |
| 827 (0.1.2: 28 January 2008; r116) | |
| 828 | |
| 829 | |
