Hi Debojyoti, Yes, I would say this is the most straightforward way of conducting this search. Note that you may need to make further adjustments to the variable mod string settings if, say, a given peptide must have *all* of its Cysteines in one state (+50) or the other (+90). The default is to allow for mixed Cysteines in the peptide, e.g. PEPC[50]TIDEC[90]R. Hope this helps, --Luis
