Description

Computes cytosine methylation and callable SNV mutations, optionally in reference to a germline BAM to call somatic variants

Description
Pattern

meta (map)

Groovy Map containing sample information
e.g. [ id:‘test’, single_end

]

normal_bams (file)

BAM files to be analyzed. If no tumor_bam file is provided, any number of “normal” BAMs may be provided
(“normal” here is just a semantic issue, these BAMs could be from tumor or any other kind of tissue). If a
tumor BAM file is provided, exactly one normal (germline) BAM must be provided.

*.{bam}

normal_bais (file)

BAM index file or files corresponding to the provided normal_bams

*.{bai}

tumor_bam (file)

Optional. If a tumor BAM file is provided, pileup will run in “somatic” mode and will annotate variants with
their somatic state (present in tumor only, present in normal only, present in both, etc). Note that if a
tumor BAM file is provided, exactly one normal BAM must be provided.

*.{bam}

tumor_bai (file)

Optional. BAM index file corresponding to provided tumor_bam

*.{bai}

index (directory)

Biscuit genome index directory (generated with ‘biscuit index’)
