LCMS data in polarity switch- XCMS- MSconvert parameters


Just received that question today, "What should I do if I have polarity switch (POS/NEG) LCMS data files ?"

The answer is if you want to process them in W4M with xcms you should split the file in 2: One for NEG one for POS using Msconvert it's easy just add the Subset option like below

Hi Yann,

As you provided the solution in the initial issue, I add this simple post to be able to tag this issue as resolved (not that I have anything to do with the resolution of course!).

Best regards
