345 **What is does**
|
|
|
346
|
|
|
347 From http://arxiv.org/abs/1303.3997:
|
|
|
348
|
|
|
349 BWA-MEM is a new alignment algorithm for aligning sequence reads or long query sequences against a large reference genome such as human.
|
|
|
350 It automatically chooses between local and end-to-end alignments, supports paired-end reads and performs chimeric alignment.
|
|
|
351 The algorithm is robust to sequencing errors and applicable to a wide range of sequence lengths from 70bp to a few megabases.
|
|
|
352 For mapping 100bp sequences, BWA-MEM shows better performance than several state-of-art read aligners to date.
|
|
|
353
|
|
|
354 It is best suited for mapping long (>70 nt) reads against large reference genomes.
|
|
|
355
|
|
|
356 This Galaxy tool wraps bwa-mem module of bwa read mapping tool. Galaxy implementation takes fastq files as input and produces output in BAM (not SAM) format, which can be further processed using various BAM utilities exiting in Galaxy (BAMTools, SAMTools, Picard).

360 **Galaxy-specific option**
|
|
|
361
|
|
|
362 Galaxy allows four levels of control over bwa-mem options provided by **Select analysis mode** menu option. These are:
|
|
|
363
|
|
|
364 1. *Simple Illumina mode*: The simplest possible bwa mem application in which it alignes single or paired-end data to reference using default parameters. It is equivalent to the following command: bwa mem <reference index> <fastq dataset1> [fastq dataset2]
|
|
|
365 2. *PacBio mode*: The mode adjusted specifically for mapping of long PacBio subreads. Equivalent to the following command: bwa mem -k17 -W40 -r10 -A1 -B1 -O1 -E1 -L0 <reference index> <PacBio dataset in fastq format>
|
|
|
366 3. *Full list of options*: Allows access to all options through Galaxy interface.

370 **BWA MEM options**

371
|
|
|
372 Each Galaxy parameter widget corresponds to command line flags listed below:
|
|
|
373
|
|
|
374 Algorithm options::
|
|
|
375
|
|
|
376 -k INT minimum seed length [19]
|
|
|
377 -w INT band width for banded alignment [100]
|
|
|
378 -d INT off-diagonal X-dropoff [100]
|
|
|
379 -r FLOAT look for internal seeds inside a seed longer than {-k} * FLOAT [1.5]
|
|
|
380 -y INT find MEMs longer than {-k} * {-r} with size less than INT [0]
|
|
|
381 -c INT skip seeds with more than INT occurrences [500]
|
|
|
382 -D FLOAT drop chains shorter than FLOAT fraction of the longest overlapping chain [0.50]
|
|
|
383 -W INT discard a chain if seeded bases shorter than INT [0]
|
|
|
384 -m INT perform at most INT rounds of mate rescues for each read [50]
|
|
|
385 -S skip mate rescue
|
|
|
386 -P skip pairing; mate rescue performed unless -S also in use
|
|
|
387 -e discard full-length exact matches
|
|
|
388
|
|
|
389 Scoring options::
|
|
|
390
|
|
|
391 -A INT score for a sequence match, which scales options -TdBOELU unless overridden [1]
|
|
|
392 -B INT penalty for a mismatch [4]
|
|
|
393 -O INT[,INT] gap open penalties for deletions and insertions [6,6]
|
|
|
394 -E INT[,INT] gap extension penalty; a gap of size k cost '{-O} + {-E}*k' [1,1]
|
|
|
395 -L INT[,INT] penalty for 5'- and 3'-end clipping [5,5]
|
|
|
396 -U INT penalty for an unpaired read pair [17]
|
|
|
397
|
|
|
398 Input/output options::
|
|
|
399
|
|
|
400 -p first query file consists of interleaved paired-end sequences
|
|
|
401 -R STR read group header line such as '@RG\tID:foo\tSM:bar' [null]
|
|
|
402
|
|
|
403 -v INT verbose level: 1=error, 2=warning, 3=message, 4+=debugging [3]
|
|
|
404 -T INT minimum score to output [30]
|
|
|
405 -h INT if there are <INT hits with score >80% of the max score, output all in XA [5]
|
|
|
406 -a output all alignments for SE or unpaired PE
|
|
|
407 -C append FASTA/FASTQ comment to SAM output
|
|
|
408 -V output the reference FASTA header in the XR tag
|
|
|
409 -Y use soft clipping for supplementary alignments
|
|
|
410 -M mark shorter split hits as secondary
|
|
|
411
|
|
|
412 -I FLOAT[,FLOAT[,INT[,INT]]]
|
|
|
413 specify the mean, standard deviation (10% of the mean if absent), max
|
|
|
414 (4 sigma from the mean if absent) and min of the insert size distribution.
|
|
|
415 FR orientation only. [inferred]
