Hope you all doing well.
I am analyzing LC-MS data, while there is an error in the step of adjustRtime. I feel confused about it.
The error is as follows:
Performing retention time correction using 1 peak groups.
Error in do_adjustRtime_peakGroups(chromPeaks(object, msLevel = msLevel), : **
** Not enough peak groups even for linear smoothing available!
Calls: adjustRtime → adjustRtime → .local → do_adjustRtime_peakGroups
In addition: Warning message:
In do_adjustRtime_peakGroups(chromPeaks(object, msLevel = msLevel), :
** Too few peak groups for ‘loess’, reverting to linear method**
Could someone give me suggestions？ Thank you in advance.
