Ok, it depends a lot on the settings of ppm and tolerance. I'll close this issue.
from xcms.
I just noticed an extra parameter p
in combineSpectra
. This will give me one spectrum per feature.
spectra_closest_combine <- Spectra::combineSpectra(x = spectra_closest,
FUN = Spectra::combinePeaks,
tolerance = 0.025,
ppm = 100,
peaks = "union",
intensityFun = base::mean,
mzFun = base::mean,
f = spectra_closest$feature_id,
p = spectra_closest$feature_id)
Spectra::plotSpectra(spectra_closest_combine[which(spectra_closest_combine$feature_id == "FT469")])
Remains only the problem with the intensities.
