Dear All,

 I would like to view the OMSSA results with pepXMLViewer as there some
compatibility issues with the latest version of OMSSA and OMSSA Browser.

I have taken standard mgf file and run OMSSA search against it and produced
xml formatted output.

Then I have used omssa2pepXML (part of the OMSSA distribution) to generate
pepXML file. I have also generated mzXML file using latest version of the
msconvert  from the build of ProteoWizard release: 2.1.2351 (2010-11-3) on
Linux box.

I am able to view pepXML file using pepXML Viewer, but few things are
missing. When I click first few rows of the "IONS" column I am able to view
the display (not sure how much extent this display is correct) but after
that when I click any item in the same column I am getting an error message
"Error-cannot parse scan number ...".

I suspect this is due to the fact that the mzXML was generated from mgf file
which itself doesn't contain retention time information.

I wonder is there anyway I can able to produce reasonable views with mzXML
file generated from the mgf file.

Please note that I didn't have these problems when I produce mzXML file from
the RAW files.









with regards,
