Transforming the MS/MS spectrum in alignment export into a more suitable format

Hello,

I have a question related to the MS/MS data format provided in the MS/MS spectrum column in the exported alignment result file. The MS/MS fragments are listed there in ascending order of the m/z as m/z1:abundance1 m/z2:abundance2 etc. For reporting MS/MS spectra in publications, we often have a format where the most intense fragments are listed in descending order of relative intensity as follows: m/z1 (pergentage1), m/z2 (percentage2) etc.

Is there a way to automatically transform the data in the MS/MS spectrum column into another format that is more suitable to be reported as such in a publication? Perhaps someone has used an Excel macro or R script? This would be handy in case there are plenty of MS/MS spectra to report.

Thanks in advance,
Ville Koistinen

Hi Ville,

sorry I should do this, but I hope some of researchers can help you to export the spectrum list that you want...
