Optionally store the sample-vs-gene matrix used during calculations.

List of genes to test, typically SMGs. If unspecified, all genes in \s-1MAF\s0 are tested.
Skip non-coding mutations from the provided \s-1MAF\s0 file Default value 'true' if not specified
Skip silent mutations from the provided \s-1MAF\s0 file Default value 'true' if not specified
This module parses a list of mutations in \s-1MAF\s0 format and attempts to determine relationships among mutated genes. It employs a correlation test to see whether or not any two genes are mutated concurrently (positive correlation) or mutually exclusively (negative correlation). Because of the possibility of largely varying numbers of mutations present in different genes, P-values are calculated using restricted permutations that take into account the distribution of mutation counts among the samples. In the output file, 'pand' is the P-value for concurrent mutation events, and 'pexc' is the P-value for mutually exclusive mutation events.
