Hi, Can anyone shed some light on why the "Mixture model quality test failed for charge (2+) and (3+)". They are the majority of my spectra and I get good hyperscores especially from the 3+ spectra prior to xinteract command. I do not feel my data is bad, but apparently peptide prophet cannot make anything out of it...
I'm using TPP 4.4.0 on Mac (gui and command line), but I can reproduce the error on the windows TPP 4.4.0. (also gui and command line). Thanks, Bjorn PeptideProphet (TPP v4.4 VUVUZELA rev 0, Build 201008200839 (linux)) akel...@isb read in 695 1+, 7797 2+, 9641 3+, 0 4+, 0 5+, 0 6+, and 0 7+ spectra.
