XCMS Online / Error using converted Waters LCT data
Hi,

After uploading converted LCT waters.RAW (to mzXML using pwiz) I am getting an error on the status of my data sets.

The error reads: "Error in xcmsRaw(file, profstep = 0) : Time for scan 1691 (599.832) greater than scan 1692 (12.347)"

Any ideas what the problem is?

Thanks,

Mike Dickinson.

XCMS Online / Erro - "No MS1 data?"
Hi,

I am a first time user of XCMS Online and am having some difficulties. I have uploaded 2 data sets of converted (to mzXML) thermo exactive data.
I've tried 2 parameter settings - HPLC-Orbitrap and HPLC Single Quad. On both occassions I have recieved the error - "No MS1 data?"

Is it my parameter setting that is causing this problem, what setting should be used for Exactive data? I have had no problems on other software packages with these mzXML files.

Thanks.
