Hi, I independently used both Trapper (4.3.1) and Msconvert (pwiz 1.6.0) to convert a 1.4Gb Agilent MassHunter ".d" file containing ~16000 spectra to mzXML.
Parameters: $msconvert --mzXML --verbose large.d $trapper --mzXML -v large.d large.mzXML Msconvert took 5hrs 38mins to complete, generating a 57Gb file. Trapper took 1hr 26mins to complete, generating a 28Gb file. I can understand the differences in size, given the differences in structure and precision. However, the time difference still appears quite high. One interesting observation is that msconvert does not start writing to the output file until 1hr 20min has elapsed. At that point, the file begins filling and the progress messages start appearing in the output. Trapper, on the other hand, starts filling the output file and reporting progress immediately. I have seen this occur now for two runs on two different days, so I don't think it's related to other activity on the machine. Perhaps msconvert is engaging in some preprocessing that isn't strictly necessary, for Agilent ".d" files at least?
