Hi Ralf,

Thanks, that answers my question about S/N. What is your approach with respect to intb? Is there an argument to be made for not filling in intb or is that an outstanding error/issue?

This method does not calculate comparable S/N values for these features that get filled up.

I'm just getting really started on metabolomics work (well, restarted), and so I am unclear on how to proceed with these NAs. I wonder if it is appropriate to estimate intb and sn for these peaks whose intensities (into, maxo) are estimated by fillPeaks? What is your opinion and what do you do for your own work?
