adding sample annotation after PeakPicking and RTcorrection?

Hello all,

I am trying to preprocess my LCMS data, and now at the point of correspondance, which (as I understand) relies on knowing the type of the sample to filter out the peaks present in too few of replicas. But apparently I never read in my sample annotation file, so my xdata file does not have a $sample_group column. Is there a way to add the annotation now or do I have to start over again?

Best,
Lisa
