Notes about R/Bioc for proteomics.

Ideas:

• Label-free quantification
• MS QC support (integration with QuaMeter from David Tabb). Related: qcmetrics for a general framework to define and bundle QC items and msQC.
• Better fragmentation pattern prediction for spectra annotation - what is, if any, already available?
• Add handling modifications
• Add deisotoping capability - what is, if any, already available? Need to look up if this capability is available in other packaged. However it is quite unlikely. The good old algorithm for this kind of task is THRASH (http://www.ncbi.nlm.nih.gov/pubmed/10757168). It has been implemented in this GUI only standalone software (http://omics.pnl.gov/software/decontools-decon2ls)
