The trick with problem sets so sparsely filled with noteworthy information is skipping as many processing steps as possible without marring the final results by skipping something important. I have made some modifications to GFS and am testing those now: If MSMSFit goes through all of the y-ions and finds less than 12% match then [...] Read More

“Tandem mass data hash,” try to say that five times fast. To get a better feel for how MS/MS data will be represented as a hash I wrote a quick visualizer. How the MSMS data is hashed: an NxM bin matrix is computed where N is the number of bins to store mass and M [...] Read More

This was confusing the hell out of me. I’d have an fprintf call that would say something like “loading spectra…” and a breakpoint before that and in the console it would still print “loading spectra…” and continue on its merry way like the breakpoint didn’t even exist. So what’s the real problem? I don’t know [...] Read More

I’m curious if a job on one DTA/PKL file with N spectra will run faster than a job that processes the exact same data broken into N different files. I just wrote a quick java app to take OutputFile2.dta which has 112 spectra and split it into 112 different dta files. At the moment I [...] Read More
