Very useful software but… how can I import a txt file to OpenChrom?
And what the sintax that the file must have to be read as a mass spectrum?
Thank a lot,
Duma.
Hi nerduma,
OpenChrom supports a CSV converter to read and write chromatograms. You can download it free of charge from the marketplace. Watch the tutorial on YouTube (http://www.youtube.com/watch?v=7S6bFx8jcHw)
Use the output file as a documentation if you’d like to import edited chromatograms.
Thank you eselmeister!
I’ve installed CSV from Eclipse MarketPlace and restart OpenChrom.
If I try to open my text file with the mass spectrum (is only a list of M/z and rel. abundance ), it open the file as a text file, not a spectrum.
Is possible to open as a spectrum (and use the NIST identifier) to a file like this:

Yes, that’s correct. It will not work, cause the CSV converter expects to import a complete chromatogram. Single mass spectra can be not loaded at the moment, but the upcoming 0.6.0 release will contain a plug-in for a batch wise peak identification (http://sourceforge.net/projects/peakidentbatch). The plug-in is still in progress and is designed to batch identify peaks detected by PARAFAC algorithms. In a way, it could be also used as a workaround to identify mass spetra. Further more, it should be also possible to identify lists of mass spectra, but I can’t guarantee to finish such a plug-in, cause there are already thousand things on my list. You can also write me an email (http://www.openchrom.net/main/content/contact.php) to keep you updated.
