Description Usage Arguments Details Examples

View source: R/mutsigcv.sig.pathway.R

Description

Identify significantly mutated pathways (SMP) through combining p-values that computed for each gene, e.g. output produced by MutSigCV.

Usage

1
mutsigcv.sig.pathway(mutsigcv.sig_gene.filename, pathway, out.filename=NA, exclude.genes=c(), min.n_nonsilent=0)

Arguments

mutsigcv.sig_gene.filename

Output file generated by MutSigCV, often ended with .sig_genes.txt.

pathway

A data frame with 3 cols containg pathway information, see details for detail.

out.filename

output file.

exclude.genes

Genes to be excluded.

min.n_nonsilent

min number of nonsilent mutations required.

Details

Identification of SMPs based on combining p-values.

pathway, a data frame, with 3 columns, for example:

PathwayID PathwayName Genes
pathway1 RB signaling A,B,C,D,E
pathway2 TP53 signaling C,D,F,G,H
