I am trying to process data from a UPLC-QTOF experiment using centWave. However, I've realized that my mzXML files contain data in profile mode, not centroid. The data have come from another lab, so I don't have an easy way to re-obtain the original .d files.
My questions are:
1) Is there an alternative to centWave that will handle high resolution spectra in profile mode?
2) Is there a way to convert mzXML files in profile mode to centroid mode? Keep in mind that I don't have the original files in .d format.
Thanks!

1) I don't think so
2) Yes. you can use msconvert from proteowizard to re-convert the files and centroid the data. The peakPicking filter should be what you need.
