If any Bismark function is missing please contact the tool author or your Galaxy admin. - ------- - -**Bismark parameter list** - -This is an exhaustive list of Bismark options: - ------- - -**OPTIONS** - - -Input:: - - --singles A comma- or space-separated list of files containing the reads to be aligned (e.g. - lane1.fq,lane2.fq lane3.fq). Reads may be a mix of different lengths. Bismark will - produce one mapping result and one report file per input file. - - -1 mates1 Comma-separated list of files containing the #1 mates (filename usually includes - "_1"), e.g. flyA_1.fq,flyB_1.fq). Sequences specified with this option must - correspond file-for-file and read-for-read with those specified in mates2. - Reads may be a mix of different lengths. Bismark will produce one mapping result - and one report file per paired-end input file pair. - - -2 mates2 Comma-separated list of files containing the #2 mates (filename usually includes - "_2"), e.g. flyA_1.fq,flyB_1.fq). Sequences specified with this option must - correspond file-for-file and read-for-read with those specified in mates1. - Reads may be a mix of different lengths. - - -q/--fastq The query input files (specified as mate1,mate2 or singles are FASTQ - files (usually having extension .fg or .fastq). This is the default. See also - --solexa-quals. - - -f/--fasta The query input files (specified as mate1,mate2 or singles are FASTA - files (usually havin extension .fa, .mfa, .fna or similar). All quality values - are assumed to be 40 on the Phred scale. - - -s/--skip INT Skip (i.e. do not align) the first INT reads or read pairs from the input. - - -u/--upto INT Only aligns the first INT reads or read pairs from the input. Default: no limit. - - --phred33-quals FASTQ qualities are ASCII chars equal to the Phred quality plus 33. Default: on. - - --phred64-quals FASTQ qualities are ASCII chars equal to the Phred quality plus 64. Default: off. - - --solexa-quals Convert FASTQ qualities from solexa-scaled (which can be negative) to phred-scaled - (which can't). The formula for conversion is: - phred-qual = 10 * log(1 + 10 ** (solexa-qual/10.0)) / log(10). Used with -q. This - is usually the right option for use with (unconverted) reads emitted by the GA - Pipeline versions prior to 1.3. Works only for Bowtie 1. Default: off. - - --solexa1.3-quals Same as --phred64-quals. This is usually the right option for use with (unconverted) - reads emitted by GA Pipeline version 1.3 or later. Default: off. - - -Alignment:: - - -n/--seedmms INT The maximum number of mismatches permitted in the "seed", i.e. the first L base pairs - of the read (where L is set with -l/--seedlen). This may be 0, 1, 2 or 3 and the - default is 1. This option is only available for Bowtie 1 (for Bowtie 2 see -N). - - -l/--seedlen The "seed length"; i.e., the number of bases of the high quality end of the read to - which the -n ceiling applies. The default is 28. Bowtie (and thus Bismark) is faster for - larger values of -l. This option is only available for Bowtie 1 (for Bowtie 2 see -L). - - -e/--maqerr INT Maximum permitted total of quality values at all mismatched read positions throughout - the entire alignment, not just in the "seed". The default is 70. Like Maq, bowtie rounds - quality values to the nearest 10 and saturates at 30. This value is not relevant for - Bowtie 2. - - --chunkmbs INT The number of megabytes of memory a given thread is given to store path descriptors in - --best mode. Best-first search must keep track of many paths at once to ensure it is - always extending the path with the lowest cumulative cost. Bowtie tries to minimize the - memory impact of the descriptors, but they can still grow very large in some cases. If - you receive an error message saying that chunk memory has been exhausted in --best mode, - try adjusting this parameter up to dedicate more memory to the descriptors. This value - is not relevant for Bowtie 2. Default: 512. - - -I/--minins INT The minimum insert size for valid paired-end alignments. E.g. if -I 60 is specified and - a paired-end alignment consists of two 20-bp alignments in the appropriate orientation - with a 20-bp gap between them, that alignment is considered valid (as long as -X is also - satisfied). A 19-bp gap would not be valid in that case. Default: 0. - - -X/--maxins INT The maximum insert size for valid paired-end alignments. E.g. if -X 100 is specified and - a paired-end alignment consists of two 20-bp alignments in the proper orientation with a - 60-bp gap between them, that alignment is considered valid (as long as -I is also satisfied). - A 61-bp gap would not be valid in that case. Default: 500. - - - -Output:: - - --non_directional The sequencing library was constructed in a non strand-specific manner, alignments to all four - bisulfite strands will be reported. Default: OFF. - - (The current Illumina protocol for BS-Seq is directional, in which case the strands complementary - to the original strands are merely theoretical and should not exist in reality. Specifying directional - alignments (which is the default) will only run 2 alignment threads to the original top (OT) - or bottom (OB) strands in parallel and report these alignments. This is the recommended option - for sprand-specific libraries). - - --sam-no-hd Suppress SAM header lines (starting with @). This might be useful when very large input files are - split up into several smaller files to run concurrently and the output files are to be merged. - - --quiet Print nothing besides alignments. - - --vanilla Performs bisulfite mapping with Bowtie 1 and prints the 'old' output (as in Bismark 0.5.X) instead - of SAM format output. - - -un/--unmapped Write all reads that could not be aligned to a file in the output directory. Written reads will - appear as they did in the input, without any translation of quality values that may have - taken place within Bowtie or Bismark. Paired-end reads will be written to two parallel files with _1 - and _2 inserted in their filenames, i.e. _unmapped_reads_1.txt and unmapped_reads_2.txt. Reads - with more than one valid alignment with the same number of lowest mismatches (ambiguous mapping) - are also written to _unmapped_reads.txt unless the option --ambiguous is specified as well. - - --ambiguous Write all reads which produce more than one valid alignment with the same number of lowest - mismatches or other reads that fail to align uniquely to a file in the output directory. - Written reads will appear as they did in the input, without any of the translation of quality - values that may have taken place within Bowtie or Bismark. Paired-end reads will be written to two - parallel files with _1 and _2 inserted in theit filenames, i.e. _ambiguous_reads_1.txt and - _ambiguous_reads_2.txt. These reads are not written to the file specified with --un. - - -o/--output_dir DIR Write all output files into this directory. By default the output files will be written into - the same folder as the input file(s). If the specified folder does not exist, Bismark will attempt - to create it first. The path to the output folder can be either relative or absolute. - - --temp_dir DIR Write temporary files to this directory instead of into the same directory as the input files. If - the specified folder does not exist, Bismark will attempt to create it first. The path to the - temporary folder can be either relative or absolute. - ------- - -Bowtie 2 alignment options:: - - -N INT Sets the number of mismatches to allowed in a seed alignment during multiseed alignment. - Can be set to 0 or 1. Setting this higher makes alignment slower (often much slower) - but increases sensitivity. Default: 0. This option is only available for Bowtie 2 (for - Bowtie 1 see -n). - - -L INT Sets the length of the seed substrings to align during multiseed alignment. Smaller values - make alignment slower but more senstive. Default: the --sensitive preset of Bowtie 2 is - used by default, which sets -L to 20. This option is only available for Bowtie 2 (for - Bowtie 1 see -l). - - --ignore-quals When calculating a mismatch penalty, always consider the quality value at the mismatched - position to be the highest possible, regardless of the actual value. I.e. input is treated - as though all quality values are high. This is also the default behavior when the input - doesn't specify quality values (e.g. in -f mode). This option is invariable and on by default. - - -Bowtie 2 paired-end options:: - - --no-mixed This option disables Bowtie 2's behavior to try to find alignments for the individual mates if - it cannot find a concordant or discordant alignment for a pair. This option is invariable and - and on by default. - - --no-discordant Normally, Bowtie 2 looks for discordant alignments if it cannot find any concordant alignments. - A discordant alignment is an alignment where both mates align uniquely, but that does not - satisfy the paired-end constraints (--fr/--rf/--ff, -I, -X). This option disables that behavior - and it is on by default. - - -Bowtie 2 effort options:: - - -D INT Up to INT consecutive seed extension attempts can "fail" before Bowtie 2 moves on, using - the alignments found so far. A seed extension "fails" if it does not yield a new best or a - new second-best alignment. Default: 15. - - -R INT INT is the maximum number of times Bowtie 2 will "re-seed" reads with repetitive seeds. - When "re-seeding," Bowtie 2 simply chooses a new set of reads (same length, same number of - mismatches allowed) at different offsets and searches for more alignments. A read is considered - to have repetitive seeds if the total number of seed hits divided by the number of seeds - that aligned at least once is greater than 300. Default: 2. - - -Bowtie 2 Scoring options:: - - --score_min "func" Sets a function governing the minimum alignment score needed for an alignment to be considered - "valid" (i.e. good enough to report). This is a function of read length. For instance, specifying - L,0,-0.2 sets the minimum-score function f to f(x) = 0 + -0.2 * x, where x is the read length. - See also: setting function options at http://bowtie-bio.sourceforge.net/bowtie2. The default is - L,0,-0.2. - - -Bowtie 2 Reporting options:: - - --most_valid_alignments INT This used to be the Bowtie 2 parameter -M. As of Bowtie 2 version 2.0.0 beta7 the option -M is - deprecated. It will be removed in subsequent versions. What used to be called -M mode is still the - default mode, but adjusting the -M setting is deprecated. Use the -D and -R options to adjust the - effort expended to find valid alignments. - - For reference, this used to be the old (now deprecated) description of -M: - Bowtie 2 searches for at most INT+1 distinct, valid alignments for each read. The search terminates when it - can't find more distinct valid alignments, or when it finds INT+1 distinct alignments, whichever - happens first. Only the best alignment is reported. Information from the other alignments is used to - estimate mapping quality and to set SAM optional fields, such as AS:i and XS:i. Increasing -M makes - Bowtie 2 slower, but increases the likelihood that it will pick the correct alignment for a read that - aligns many places. For reads that have more than INT+1 distinct, valid alignments, Bowtie 2 does not - guarantee that the alignment reported is the best possible in terms of alignment score. -M is - always used and its default value is set to 10. </help> </tool>
