matchedFilter terminates too early on an EIC? September 20, 2012, 09:28:44 PM matchedFilter finds peaks in a EIC, with a max that is a parameter of the filter function. However, it looks like as soon as it hits one peak that fails the S/N threshold, it stops looking for more peaks in that EIC. This is in line 729 of xcmsRaw.R. Should it continue to look for other peaks, ignoring the current one? I've got a case where the highest one has low s/n, but there are other peaks in the EIC, at different RTs.Thanks. Quote Selected
