Retention Time Correction

June 10, 2011, 03:30:46 PM

Hi,

I am trying to run my data without a retention time correction so that I can compare data before and after the correction. However, whenever I run the data, an error message appears half way into the run.

1) Am I supposed to be setting up some specific parameters not related to the retention time parameters, i.e. feature detection "method" or "integration method" under feature detection? Are these parameters supposed to be something specific for LC/MS data?

2) Also, I would like to be able to change min peak width and max peak width to 5 and 12, specifically, as I am trying to reproduce some data and follow someone else's foot steps for this particular analysis.

Thank you very much! I appreciate your responses! I am new to XCMS but I am very excited about it, and looking forward to using it more and more!

Sincerely,
Majda

1.) No, there are no specific settings that need to be changed. There was an issue earlier that should be fixed now.
2.) Fixed, see other posting.
