XCMS Online / Retention time correction
I'm supposed to analyze my LC-Orbitrap data on XCMS, however I'm observing a retention time shift on my chromatogram.
The standard error is about 1% for a specific range in my chromatogram, and I observe about half a minute of retention time shift in a 40 minute run.
I was wondering, can XCMS successfully correct such big retention time shifts? Is there a specific standard deviation for XCMS's retention time correction?
