Title: Retention time correction
Post by: gabrieljoyce on August 15, 2019, 07:05:34 PM
Hello,

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?
