In WuyangFF95/SynSigRun: Run Mutational Signature Analysis Software Packages Using Mutational Spectra generated by SynSigGen

Run sigfit attribution on a spectra catalog file and known signatures.

Description

Run sigfit attribution on a spectra catalog file and known signatures.

Usage

RunsigfitAttributeOnly(
  input.catalog,
  gt.sigs.file,
  out.dir,
  model = "nmf",
  seedNumber = 1,
  test.only = FALSE,
  overwrite = FALSE
)

Arguments

input.catalog	File containing input spectra catalog. Columns are samples (tumors), rows are mutation types.
gt.sigs.file	File containing input mutational signatures. Columns are signatures, rows are mutation types.
out.dir	Directory that will be created for the output; abort if it already exits. Log files will be in paste0(out.dir, "/tmp").
model	Algorithm to be used to extract signatures and attribute exposures. Only "nmf" or "emu" is valid. Default: "nmf".
seedNumber	Specify the pseudo-random seed number used to run sigfit. Setting seed can make the attribution of sigfit repeatable. Default: 1.
test.only	If TRUE, only analyze the first 10 columns read in from input.catalog. Default: FALSE
overwrite	If TRUE, overwrite existing output. Default: FALSE

Details

Creates several files in paste0(out.dir, "/sa.output.rdata"). These are TODO(Steve): list the files

Value

The inferred exposure of sigfit, invisibly.
