It is developed by Heng Li at the Sanger Insitute. Li H. and Durbin R. (2009) Fast and accurate short read alignment with Burrows-Wheeler transform. Bioinformatics, 25, 1754-60. + +------ + +**Know what you are doing** + +.. class:: warningmark + +There is no such thing (yet) as an automated gearshift in short read mapping. It is all like stick-shift driving in San Francisco. In other words = running this tool with default parameters will probably not give you meaningful results. A way to deal with this is to **understand** the parameters by carefully reading the `documentation`__ and experimenting. Fortunately, Galaxy makes experimenting easy. + + .. __: http://bio-bwa.sourceforge.net/ + +------ + +**Input formats** + +BWA accepts files in Sanger FASTQ format.

You can change any of them. All of the options in BWA have been implemented here. + +------ + +**BWA parameter list** + +This is an exhaustive list of BWA options: + +For **aln**:: + + -n NUM Maximum edit distance if the value is INT, or the fraction of missing + alignments given 2% uniform base error rate if FLOAT. In the latter + case, the maximum edit distance is automatically chosen for different + read lengths. [0.04] + -o INT Maximum number of gap opens [1] + -e INT Maximum number of gap extensions, -1 for k-difference mode + (disallowing long gaps) [-1] + -d INT Disallow a long deletion within INT bp towards the 3'-end [16] + -i INT Disallow an indel within INT bp towards the ends [5] + -l INT Take the first INT subsequence as seed. If INT is larger than the + query sequence, seeding will be disabled. For long reads, this option + is typically ranged from 25 to 35 for '-k 2'. [inf] + -k INT Maximum edit distance in the seed [2] + -t INT Number of threads (multi-threading mode) [1] + -M INT Mismatch penalty. BWA will not search for suboptimal hits with a score + lower than (bestScore-misMsc). [3] + -O INT Gap open penalty [11] + -E INT Gap extension penalty [4] + -c Reverse query but not complement it, which is required for alignment + in the color space. + -R Proceed with suboptimal alignments even if the top hit is a repeat. By + default, BWA only searches for suboptimal alignments if the top hit is + unique. Using this option has no effect on accuracy for single-end + reads. It is mainly designed for improving the alignment accuracy of + paired-end reads. However, the pairing procedure will be slowed down, + especially for very short reads (~32bp). + -N Disable iterative search. All hits with no more than maxDiff + differences will be found. This mode is much slower than the default. + +For **samse**:: + + -n INT Output up to INT top hits. Value -1 to disable outputting multiple + hits. NOTE: Entering a value other than -1 will result in output that + is not in SAM format, and therefore not usable further down the + pipeline. Check the BWA documentation for details on the format of + the output. [-1] + +For **sampe**:: + + -a INT Maximum insert size for a read pair to be considered as being mapped + properly. Since version 0.4.5, this option is only used when there + are not enough good alignment to infer the distribution of insert + sizes. [500] + -o INT Maximum occurrences of a read for pairing. A read with more + occurrences will be treated as a single-end read. Reducing this + parameter helps faster pairing. [100000] + + </help> + <code file="bwa_wrapper_code.py" /> +</tool> + +
