Title: XCMS MS/MS
Post by: masoud zabet on February 27, 2018, 02:01:11 PM
Hello,
I am new in this forum and also XCMS. I am trying to analyse lipids from my serum samples using XCMS. I uploaded my RAW data to start the search and my run has both ms and ms/ms data. I did the analysis and got many metabolite IDs. I wanted to know if the metabolites ID I got is based on HRMS on MS level (my mass tolerance was 5 ppm) or that includes the ms/ms data as well? because for each m/z value in the list I obtained, I have several metabolites (with mass accuracy, ppm, value listed next to it), so I don't know it identifies it only based the mass of metabolites or has ms/ms data as well. If so, where I can find the ms/ms data in XCMS matched to my data? I appreciate your help a lot,
Thank you,
Masoud
