How to run MutSigCV example correctly

Question

[ShirleyDai]

Hi, I am trying to run MutsigCV as indicated by enter link description here. Does someone have some ideas? Thanks

The command is:

MutSigCV('LUSC.mutations.maf','exome_full192.coverage.txt','gene.covariates.txt','my_results','mutation_type_dictionary_file.txt','chr_files_hg19')

But got the error messages:
