Restrict Retention Time

March 20, 2016, 10:05:53 PM

I have imported data (.raw files).
Is there anyway to restrict the RT used by XCMS Online.
The data file is 17 min, I only want to use 0 - 11.5 min for analysis in XCMS online.

I don't use XCMS online but in XCMS you can do it indirectly by restricting the scan range. So you figure out what scan number correspond to the time you want and set that as the limit. Be aware that as far as I recall XCMS drops empty scans so the scan numbers you see in your vendor software might not correspond perfectly.
