184 *VarScan2 Overview*
|
|
|
185
|
|
|
186 VarScan is a platform-independent mutation caller for targeted, exome, and whole-genome resequencing data generated on Illumina, SOLiD, Life/PGM, Roche/454, and similar instruments. The newest version, VarScan 2, is written in Java, so it runs on most operating systems.

|
188 http://www.ncbi.nlm.nih.gov/pubmed/19542151
|
|
|
189
|
|
|
190 *VarScan* requires mpileup formatted input files, which are generally derived from BAM files. Since mpileup files can become humongous, the interim step of storing it is bypassed. Thus, in this wrapper one or multiple BAM/SAM files go in, get processed into a mpileup file and get directly linked to VarScan.
|
|
|
191 The samtools package is not able to parallelize the mpileup generation which make it a very slow process.
|
|
|
192 Other people were aware of this and have written a version that can do parallelization:
|
|
|
193 https://github.com/mydatascience/parallel-mpileup
|
|
|
194
|
|
|
195 Consequently, when a BAM files gets processed by this wrapper, it's processed by *parallel-mpileup* before its send to VarScan.

|
|
|
199 **Input formats**
|
|
|
200
|
|
|
201 VarScan2 accepts sequencing alignments in the same, either SAM or BAM format (http://samtools.sourceforge.net/). The alignment files have to be linked to a reference genome by galaxy. This is indicated under every history item with e.g.: *"database: hg19"* for a link to hg19, or *"database: ?"* if the link is missing.
|
|
|
202
|
|
|
203 **Installation**
|
|
|
204
|
|
|
205 Make sure your reference genomes are properly annotated in "tool-data/all_fasta.loc", and linked to the names of the reference used for alignment.
