From COSMIC mutations to MAF files

Question

[fernandov]

Hello, I downloaded the mutation file CosmicMutantExport, containing all mutation from the mutation database COSMIC. From this file I want to discriminate driver mutations from passenger mutations using the program MutSigCV. But this program requiers a MAF file. Now, I believe that the file CosmicMutantExport have all the information needed to create a MAF file, but I don't know how to make it.

The data of CosmicMutantExport: can be checked in http://cancer.sanger.ac.uk/cosmic/download at COSMIC Mutation Data.

So, my question is, do you know a method or application to make the MAF file from CosmicMutantExport?

Any help is appreciated, thanks in advance and apologies for the english.

Perhaps your question is answered here? How to use MutSigCV correctly

thanks for the comment, but the problem in that question seems to be producing the MAF file from raw sequenced data, Am I wrong?, and in my case the data is processed and the mutations described, but in another format. So, the process seems to be different.
