centWave - help October 04, 2011, 05:09:12 AM Hey everyone,I have some cdf files of HPLC-MS samples. Sometimes, when I try the centWave algorithm I get the error message SIZE_PEAKBUFS too small ! I think it is because the file is in profile and not centroid mode. Can anyone confirm this? The problem is that most of my samples are in centroid mode, but I suspect a few might be in profile...Also, when I try using parameters like this, which I see everyone mentioning here in the forum (this example was posted by hpbenton on another centWave related thread) xr<-xcmsRaw(file, profstep=0 peaks<-findPeaks.centWave(xr, snthresh = 10,ppm=3,prefilter = c(3,150),peakwidth=c(5,60),mzCenterFun="wMean",integrate = 1,fitgauss= TRUE,noise = 100)I get the unused arguments error... Shouldn't it work right away?Thanks in advance Quote Selected
