Dear all,

I'm trying to run qualscore to retrieve any non-matching spectra for 
re-matching against additional RNASeq-derived protein databases, however 
qualscore doesn't output any spectra (and returns NaN coefficients) even 
though it mentions there are unassigned spectra (15194) after the initial 
search against canonical protein sequences.

These are the issued commands leading up to the problem:

   - Converting mzML to mzXML
   - msconvert

      -o /home/job/outputProt/convertedInputFiles --filter "peakPicking true

      --mzXML

      - Retrieving non-matched high-quality spectra :(
   - java -jar -Xmx8096m qualscore_v1.0_2.jar -lp -c 1.0 -p 0.1 
      peppro_1524_F_ReneBraakman_141114_005_hilic_pool_6_most_int.pep.xml
   
It outputs the following:

Viewing the ..qual.coef file shows all coefficients to be outputted as NaN.
Does anyone know a fix or alternate method to retrieve non-matching 
high-quality spectra? (I could write a custom script that does this but I'd 
rather not reinvent the wheel ;) )

Thanks for any help!

Kind regards,

Job
