Feature detection → LC-IMS-MS → IMS expander.
The IMS expander searches for data points in mobility scans for existing features.
If selected, a tolerance will be applied to the feature's detected m/z while searching for data
points in mobility dimension. Otherwise, the accepted m/z range is determined by the feature's m/z
distribution in accumulated frame spectra.
Recommended setting: selected, 0.003 m/z and 15 ppm
Raw data instead of thresholded¶
Enables searching in mobility scan raw data instead of the thresholded (=mass detected) data. Only possible for centroid raw data files.
Override default mobility bin width (scans)¶
If selected, the default number of binned mobility scans can be overriden. Useful for data with high mobility resolution.
