roi-file Text Tab delimited list of ROIs [chr start stop gene_name] (See Description) reference-sequence Text Path to reference sequence in FASTA format normal-tumor-bam-pair Text Tab delimited line with sample name, path to normal bam file, and path to tumor bam file (See Description)
output-file Text Output file path. Specify either output-file or output-directory. output-dir Text Output directory path. Specify either output-file or output-directory normal-min-depth Integer The minimum read depth to consider a Normal BAM base as covered Default value '6' if not specified tumor-min-depth Integer The minimum read depth to consider a Tumor BAM base as covered Default value '8' if not specified min-mapq Integer The minimum mapping quality of reads to consider towards read depth counts Default value '20' if not specified
This script counts bases with sufficient coverage in the ROIs of each gene in the given pair of tumor-normal BAM files and categorizes them into - AT, CG (non-CpG), and CpG counts. It also adds up these base-counts across all ROIs of each gene in the 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). ROIs from the same chromosome must be listed adjacent to each other in this file. This allows the underlying C-based code to run much more efficiently and avoid re-counting bases seen in overlapping ROIs (for overall covered base counts). For per-gene base counts, an overlapping base will be counted each time it appears in an ROI 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 FASTA format. If a reference sequence index is not found next to this file (a .fai file), it will be created. --normal-tumor-bam-pair "sample-name path/to/normal_bam path/to/tumor_bam" --output-file Specify an output file where the per-ROI covered base counts will be written
