roi-file Text

Tab-delimited list of ROIs [chr start stop gene_name] (See Description)

reference-sequence Text

Path to reference sequence in \s-1FASTA\s0 format

wig-list Text

Tab-delimited list of \s-1WIG\s0 files [sample_name wig_file] (See Description)

output-dir Text

Directory where output files and subdirectories will be written

This script counts bases with sufficient coverage in the ROIs of each gene from given wiggle track format files, and categorizes them into - \s-1AT\s0, \s-1CG\s0 (non-CpG), and CpG counts. It also adds up these base-counts across all ROIs of each gene for each sample, but covered bases that lie within overlapping ROIs are not counted more than once towards these total counts.

--roi-file

The regions of interest (ROIs) of each gene are typically regions targeted for sequencing or are merged exon loci (from multiple transcripts) of genes with 2-bp flanks (splice junctions). For per-gene base counts, an overlapping base will be counted each time it appears in an \s-1ROI\s0 of the same gene. To avoid this, be sure to merge together overlapping ROIs of the same gene. BEDtools' mergeBed can help if used per gene.

--reference-sequence

The reference sequence in \s-1FASTA\s0 format. If a reference sequence index is not found next to this file (a .fai file), it will be created.

--wig-list

Provide a file containing sample names and the wiggle track format file locations for each. Use the tab-delimited format [sample_name wig_file] per line. Additional columns like clinical data are allowed, but ignored. The sample_name must be the same as the tumor sample names used in the \s-1MAF\s0 file (16th column, with the header Tumor_Sample_Barcode).

--output-dir

Specify an output directory where the following will be created/written: roi_covgs: Subdirectory containing per-ROI covered base counts for each sample. gene_covgs: Subdirectory containing per-gene covered base counts for each sample. total_covgs: File containing the overall non-overlapping coverages per sample.
