Hi,

I am running into troubles with the Mascot2XML command on the TPP.
I followed the steps specified in the TPP wiki:
basically file.mzXML => file.mgf conversion => Mascot searching =>
Fxxx.dat => renamed file.dat
I copy the file.dat where the original mzXML is, and with the
database. I run the command:
Mascot2XML file.dat -D./database.fasta

Here start the troubles: I get tons of warnings like:

"Warning: could not find scan numbers of spectrum
spectrumId=3974Polarity=PositiveScanMode=MassScanTimeInSeconds=3916.82
Set to 0000"

(though again, the mzXML file with the same name is in the very same
directory).
But ok...

Now the last error is more puzzling:

" 998.   opening
Thu_Sep_10_17-19-28_2009.spectrum937.0000.0000.4.out
econds=1745.3.out
 error: only found 1 periods in
spectrumId=1472Polarity=PositiveScanMode=MassScanTimeInSeconds=1428.2
"

And then, when I look into the created file.pep.xml, the file seems
truncated at the end:

"    <spectrum_query
spectrum="spectrumId=1472Polarity=PositiveScanMode=MassScanTimeInSeconds=1428.2"

No ending like in regular .pep.xml files as it should (
"</spectrum_query>
</msms_run_summary>
</msms_pipeline_analysis>"
at least!!)

Of course, no chance to start an xinteract on that truncated
file.pep.xml

So do I do anything wrong? I could not process mascot .dat files
neither from an old 2.1 nor from a newer 2.2.06. For both of those,
the .dat files gave the same problems. Also this error is reproducible
on TPP 4.0 and the latest release I could test.

Do you have any idea how to help this out?

Finally, maybe a very stupid question, but Mascot is also able to
export results in the pepXML format. But the resulting file is not
processed by xinteract. That's a pity because that would be a serious
shortcut instead of running into the "Mascot2XML" business. Any idea
why xinteract cannot process the Mascot's pepxml files?

Thanks in advance for you feedbacks.

Ludovic
