1 BWA-MEM wrapper
|
|
2 ===============
|
|
3
|
|
4 This is a wrapper for BWA_, a software package for mapping low-divergent sequences against a large reference genome. This wrapper supports only the latest algorithm, BWA-MEM, which is generally recommended for high-quality queries as it is faster and more accurate. BWA-MEM also has better performance than BWA-backtrack for 70-100bp Illumina reads.

10 Configuration
|
|
11 -------------
|
|
12
|
|
13 bwa_mem tool may be configured to use more than one CPU core by selecting an appropriate destination for this tool in Galaxy job_conf.xml file (see https://wiki.galaxyproject.org/Admin/Config/Jobs and https://wiki.galaxyproject.org/Admin/Config/Performance/Cluster ).
|
|
14
|
|
15 If you are using Galaxy release_2013.11.04 or later, this tool will automatically use the number of CPU cores allocated by the job runner according to the configuration of the destination selected for this tool.
|
|
16
|
|
17 If instead you are using an older Galaxy release, you should also add a line
|
|
18
|
|
19 GALAXY_SLOTS=N; export GALAXY_SLOTS
|
|
20
|
|
21 (where N is the number of CPU cores allocated by the job runner for this tool) to the file
|

|

28 - Release 0: Initial release in the Tool Shed. This is a fork of http://toolshed.g2.bx.psu.edu/view/yufei-luo/bwa_0_7_5 repository with the following changes: Remove .loc file, only .loc.sample should be included. Fix bwa_index.loc.sample file to contain only comments. Add suppressHeader param as in bwa_wrappers. Use $GALAXY_SLOTS environment variable when available. Add <version_command> and <help>. Remove unused import. Fix spacing and typos. Use new recommended citation. Add tool_dependencies.xml . Rename to bwa_mem. Remove definitively colorspace support. Use optparse instead of argparse since Galaxy still supports Python 2.6 .
