XCMS Online / Error: WRONG_POLARITY
I created mzML files with msconvert (command line version)

Parameters:

filter="peakPicking true 1-"
filter="msLevel 1"
filter="sortByScanTime"
polarity=positive
zlib=true

When I try to run them in XCMSOnline, I get "ERROR, WRONG_POLARITY"

An incorrect polarity parameter was selected in the parameter settings for the datafiles being run. Please check the polarity of the uploaded files and rerun with the correct polarity settings.

My XCMS parameters are set to positive using HPLC/Orbitrap.

Am I doing something wrong?
