When working with centroided data, it makes more sense to use a m/z or ppm tolerance to extract chromatograms. Once the data is centroided, the peak resolution in the m/z dimension is irrelevant, since all peaks have been reduced to a single point in the m/z dimension. This can have a negative impact on quantification, but for centroided data, the mass accuracy in m/z dimension becomes more important than the peak resolution prior to centroiding.

Therefore, it would be useful to allow m/z or ppm tolerance for chromatogram extraction in centroided data.

Sorry, Stephanie, this will have to wait until winter.

This is fixed by the new "Centroided" mass analyzer type implemented in v3.5
