| 319 **What is does** | |
| 320 | |
| 321 From http://arxiv.org/abs/1303.3997: | |
| 322 | |
| 323 BWA-MEM is a new alignment algorithm for aligning sequence reads or long query sequences against a large reference genome such as human. | |
| 324 It automatically chooses between local and end-to-end alignments, supports paired-end reads and performs chimeric alignment. | |
| 325 The algorithm is robust to sequencing errors and applicable to a wide range of sequence lengths from 70bp to a few megabases. | |
| 326 For mapping 100bp sequences, BWA-MEM shows better performance than several state-of-art read aligners to date. | |
| 327 | |
| 328 It is best suited for mapping long (>70 nt) reads against large reference genomes. | |
| 329 | |
| 330 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). | |

336 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: |

338 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. |

339 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`. |

| 0 | 348 **Galaxy-specific option** |
| 349 | |
| 350 Galaxy allows four levels of control over bwa-mem options provided by **Select analysis mode** menu option. These are: | |
| 351 | |
| 352 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] | |
| 353 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> | |
| 354 3. *Full list of options*: Allows access to all options through Galaxy interface. | |
