Other / Running msconvert with R?
Hi all,

I am trying to run MSConvert with R, but I got 127 error. What could be the problem?

Code: [Select]
msconvert <- "C:/Program Files (x86)/ProteoWizard/ProteoWizard 3.0.21175.5b6d9afee/msconvert.exe"
file <- "C:/Users/Desktop/Data/QC1.raw"
outfile <- "C:/Users/Desktop/Data"
convert <- paste0(msconvert," --mzXML, -o outfile -v", file)

Thanks for your help.

CAMERA / Feature selection for downstream statistics
Hi CAMERA users,

I want to perform statistics using the features generated by CAMERA, but I don't want to use all of them because many features represent the same "metabolite".

As features with the same PC label are supposed to belong to the same spectrum, can I just use features with a pattern of absence and a monoisotopic annotation for statistics?

Or do you have some other suggestions?

Thanks a lot.
