[BioC] Mass spectrometry data analysis

[James W. MacDonald]

Hi all,

I see lots of packages in BioC for the analysis of raw mass spectrometry 
data, but I don't see anything offhand for the differential analysis of 
these data. In addition, the googles seem only to point towards 
proprietary analysis software.

I have been handed a data set comprised of spectral counts (rather than 
say, area under the curve), and wonder if anybody has experience with 
this type of data, and might have pointers to useful software.

Best,

Jim
