Hi,

I'm using SomaticSignatures package and i would like to find the best number of signatures that i should use. I could not find assessNumberSignatures function. 

I also could not find motifMatrix function but i could find mutationContextMatrix ​instead which is the same function as in the link below.

http://127.0.0.1:12716/library/SomaticSignatures/doc/SomaticSignatures-vignette.R

#============To assess Number of Signatures

n_sigs = 2:8
gof_nmf= assessNumberSignatures(Data, n_sigs, nReplicates = 5)
>Error: could not find function "assessNumberSignatures"

Has assessNumberSignatures been deprecated?

Thank you in advance.

It seems that you are have an old version of the package, while you are looking at the documentation of the current version (e.g. online via the Bioconductor web site). Please check with biocLite and/or the package website http://bioconductor.org/packages/release/bioc/html/SomaticSignatures.html that you have the latest version installed. At the time of writing, this is 2.4.5.

Thanks Julian. It works now
