An optional category for truncational mutations can also be specified. The script generates a file with per-gene mutation rates that can be used with the tool that tests for significantly mutated genes (music smg). ## ARGUMENTS - \--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. - \--bam-list - Provide a file containing sample names and normal/tumor BAM locations for each. Use the tab- delimited format \[sample\_name normal\_bam tumor\_bam\] 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 MAF file (16th column, with the header Tumor\_Sample\_Barcode). - \--bmr-groups - Ideally, we want to test the mutation rate (MR) of a gene in a sample against the background mutation rate (BMR) across that sample. But if the BMRs of some samples are comparable, we can instead test the MR of a gene across a group of samples with comparable BMR, against the overall BMR of that group. This argument specifies how many such groups you want to cluster samples into. By default, it is assumed that all samples have comparable BMRs (bmr-groups = 1). - \--output-dir - This should be the same output directory used when running "music bmr calc-covg". The following outputs of this script will also be created/written: overall\_bmrs: File containing categorized overall background mutation rates. gene\_mrs: File containing categorized per-gene mutation rates. - \--genes-to-ignore - A comma-delimited list of genes to ignore for overall BMR calculations. List genes that are known factors in this disease and whose mutations should not be classified as background. ## LICENSE Copyright (C) 2010-2011 Washington University in St. Louis.
