Hi Bosco,
You have the right formula. The issue is that some of the reported numbers
may be rounded up or down, so that entries with weights of 0.4 and
0.50001 will be recorded as 0.50 in the protXML file. The
num_unique_peptides should match the ones that have
is_contributing_evidence set to
I'm trying to reproduce the calculation of the num_unique_peptides.
If I use (peptide.weight > 0.5 and peptide.nsp_adjusted_prob >= 0.2), I
seem to get most of them, but I still miss a few.
Anyone have an idea to how it's calculated?
Bosco.
