**What is does**

From http://arxiv.org/abs/1303.3997:

BWA-MEM is a new alignment algorithm for aligning sequence reads or long query sequences against a large reference genome such as human.
It automatically chooses between local and end-to-end alignments, supports paired-end reads and performs chimeric alignment.
The algorithm is robust to sequencing errors and applicable to a wide range of sequence lengths from 70bp to a few megabases.
For mapping 100bp sequences, BWA-MEM shows better performance than several state-of-art read aligners to date.

It is best suited for mapping long (>70 nt) reads against large reference genomes.

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).

-----

**Indices: Selecting reference genomes for BWA**

Galaxy wrapper for BWA allows you select between precomputed and user-defined indices for reference genomes using **Will you select a reference genome from your history or use a built-in index?** flag. This flag has two options:

  1. **Use a built-in genome index** - when selected (this is default), Galaxy provides the user with **Select reference genome index** dropdown. Genomes listed in this dropdown have been pre-indexed with bwa index utility and are ready to be mapped against.  
  2. **Use a genome from the history and build index** - when selected, Galaxy provides the user with **Select reference genome sequence** dropdown. This dropdown is populated by all FASTA formatted files listed in your current history. If your genome of interest is uploaded into history it will be shown there. Selecting a genome from this dropdown will cause Galaxy to first transparently index it using `bwa index` command, and then run mapping with `bwa mem`.
    
If your genome of interest is not listed here you have two choices:

  1. Contact galaxy team using **Help->Support** link at the top of the interface and let us know that an index needs to be added
  2. Upload your genome of interest as a FASTA file to Galaxy history and selected **Use a genome from the history and build index** option.

-----

**Galaxy-specific option**

Galaxy allows four levels of control over bwa-mem options provided by **Select analysis mode** menu option. These are:

  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 &lt;reference index&gt; &lt;fastq dataset1&gt; [fastq dataset2]
  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  &lt;reference index&gt; &lt;PacBio dataset in fastq format&gt;
  3. *Full list of options*: Allows access to all options through Galaxy interface.

------

**BWA MEM options**

Each Galaxy parameter widget corresponds to command line flags listed below:

Algorithm options::

       -k INT        minimum seed length [19]
       -w INT        band width for banded alignment [100]
       -d INT        off-diagonal X-dropoff [100]
       -r FLOAT      look for internal seeds inside a seed longer than {-k} * FLOAT [1.5]
       -y INT        find MEMs longer than {-k} * {-r} with size less than INT [0]
       -c INT        skip seeds with more than INT occurrences [500]
       -D FLOAT      drop chains shorter than FLOAT fraction of the longest overlapping chain [0.50]
       -W INT        discard a chain if seeded bases shorter than INT [0]
       -m INT        perform at most INT rounds of mate rescues for each read [50]
       -S            skip mate rescue
       -P            skip pairing; mate rescue performed unless -S also in use
       -e            discard full-length exact matches

Scoring options::

       -A INT        score for a sequence match, which scales options -TdBOELU unless overridden [1]
       -B INT        penalty for a mismatch [4]
       -O INT[,INT]  gap open penalties for deletions and insertions [6,6]
       -E INT[,INT]  gap extension penalty; a gap of size k cost '{-O} + {-E}*k' [1,1]
       -L INT[,INT]  penalty for 5'- and 3'-end clipping [5,5]
       -U INT        penalty for an unpaired read pair [17]

Input/output options::

       -p            first query file consists of interleaved paired-end sequences
       -R STR        read group header line such as '@RG\tID:foo\tSM:bar' [null]

       -v INT        verbose level: 1=error, 2=warning, 3=message, 4+=debugging [3]
       -T INT        minimum score to output [30]
       -h INT        if there are &lt;INT hits with score &gt;80% of the max score, output all in XA [5]
       -a            output all alignments for SE or unpaired PE
       -C            append FASTA/FASTQ comment to SAM output
       -V            output the reference FASTA header in the XR tag
       -Y            use soft clipping for supplementary alignments
       -M            mark shorter split hits as secondary

       -I FLOAT[,FLOAT[,INT[,INT]]]
                     specify the mean, standard deviation (10% of the mean if absent), max
                     (4 sigma from the mean if absent) and min of the insert size distribution.
                     FR orientation only. [inferred]
