Getting UV data into XCMS+ findPeaks
Hi everyone,
I would like to know if someone tried to import UV data in XCMS and then used the findPeaks function?
I have seen on the forum that some xcms users are familiar with import of UV data in xcms but i didn't see any clue on the cookbook or on the internet.
I have managed to fill an xcmsRaw object with my UV data and i can create chromatograms with plotChrom() but i didn't managed to use the findPeaks.matchedFilter(raw, ...) function
error messages
seq.default(floor(mrange[1]/step) * step, ceiling(mrange[2]/step) * :
invalid (to - from)/by in seq(.)
1: In min(x, na.rm = na.rm) : no argument find for min ; Inf
2: In max(x, na.rm = na.rm) : no argument find for max; Inf
any idea?
to fill my xcmsRaw object i have tried to fill as many slots as possible but some are still empty.
