I try to run the following code:

ms_exp <- readMsExperiment(files, sampleData = metadata)

which yields the following error:

Error: Can not open file XCMS\data_mzML\171103_PMA_TK_M1_03.mzML! Original error was: Error: Invalid cvParam accession "1002993"

I used msconvert to convert the .raw into mzML.

How can I convert .raw ms data to a format xcms can use?
