hi TPP developers,

        I challenged the PeptideProphet by analyzing ~200 pepXML
files. The command is as below (all the parameters in a single line):

c:\Inetpub\tpp-bin\xinteract  -Ninteract.pep.xml -p0.05 -l7 -O
c:/Inetpub/wwwroot/ISB/data/file1.pep.xml
c:/Inetpub/wwwroot/ISB/data/file2.pep.xml
c:/Inetpub/wwwroot/ISB/data/file3.pep.xml
c:/Inetpub/wwwroot/ISB/data/file4.pep.xml
...
...
c:/Inetpub/wwwroot/ISB/data/file200.pep.xml

         DOS failed saying "the input line is too long". GUI simply
said "Command FAILED".

         WinXP limits command length to 8191 characters. Anybody knows
how to extend the limit?

         If not, I notice the xinteract uses a full path for each
pepXML file, so the path is repeated 200 times in my command. Is it
possible to modify the program so that the full path is only once?
Maybe the file extension name ".pep.xml" is also not necessary to
occupy characters in the command.

        The best way I could suggest is to modify the command, so that
we pass a folder name as a parameter, and all the pepXML files in the
folder could be analyzed.

Thanks!

Best regards,
Tiannan
