XCMS / Correction of mass calibration gaps failed.
Hi,

I am using netCDF files data. (Waters), so to correct the Lock Mass Gap, I did selected the option "Correct mass calibration gaps" on the micellaneous of my method parameters, Online XCMS. I got this warning after processing my data :

Warning :  Correction of mass calibration gaps failed (AutoLockMass). Processing data without correction.

Any help to fix it ?

Thank you.

XCMS Online / XCMS : Processing and the number of features picked
Hi,

Do we get the same features, so the same diffreport, by processing 2 groups downloaded in 2 different datasets in one case, and by processing the same 2 groups downloaded in one dataset against blank samples in the other dataset ?

The same processing parameters were set in both methods.

Thank you for your answer.
