Re: [spctools-discuss] Question on Mascot.dat file and database.fasta file

Hi Jimmy, Yes, you are right. SSM411 is how I named my sample, and F030382 is the .DAT file name generated by MASCOT. I have renamed them by SSM411.*. I didn't convert the .mgf file using MzXML2Search ealier. I used the pkl files generated by PLGS (Waters) from .raw data to do the Mascot

There's no surprise that generating mgf files using other tools can cause Mascot to perform (much) better as those tools apply things like peak picking which MzXML2Search doesn't do. MzXML2Search pretty much just takes the input spectral data and writes it back out into the chosen output format.

Hi Brian, I ran the Mascot search again with trypsin as enzyme, instead of tryspin/P. The .dat file was able to convert to .pep.xml file successfully (cool!). Well, there is a warning at the end of the command lines, and I don't know how important this is. ... 333. opening

When charge states are not listed in the mzXML file you should run the command: MzXML2Search -mgf -c1-3 *.mzXML This will generate the mgf files to submit to Mascot. Once you get the .dat files back you should rename that to the original basename of the mzXML file with the .dat extension. Now

Actually, after a discussion on the phone with Jimmy, I think that the -c1-3 option is not needed in this case and will cause some extra searches being run. Just use MzXML2Search -mgf *.mzXML And then rename the resulting .dat file to match the input basename. -David On Mon, Jun 28, 2010 at

Hi all, I posted my questions yesterday, but they were a bit too long to read, so I shortened it (still seems long). I am trying to use TPP (4.3.1) to run some cICAT data I collected a while ago. All these cICAT data have been searched by Mascot (I have all the .dat files). So far I have not got
