i am a new user of XCMS and i have similar problem. i want to use CentWave and i have the same error message. i use centroid data but in R, i have warnings message like what my data are in profile mode
initially my files are .RAW, i convert them to mzXML with Proteowizard but i have always the message that my files are in profile mode

xset1 <- xcmsSet(method="centWave", ppm=10 ,peakwidth=c(6,30), noise= 1000000, mzdiff=0.01, prefilter=c(4,1000000), snthresh = 6,fitgauss=TRUE)
