Mutsig in Galaxy

Question

[kunaphas.kon]

I try to add mutsig tool in galaxy, but I don't know how to write output tag in mutsig.xml (configuration file) since mutsig tool, the parameter output , you only put the prefix and the program will create four files including prefix name that we define it in parameter (example: run_MutSigCV.sh <path_to_MCR> mutations.maf coverage.txt covariates.txt output, the outputs will have output.coverage.txt, output.mutations.txt, output.categs.txt, and output.sig_genes.txt)

How can I handle this task?

I really appreciate any help you can provide
