LC-IMS-MS Feature Finder

Finds LC-IMS-MS features using deisotoped features from DeconTools


The LC-IMS-MS Feature Finder finds LC-IMS-MS features and conformers using deisotoped features from DeconTools. Required files are a DeconTools _isos.csv file plus the corresponding .UIMF file if UseConformationDetection is True.

A features file is created by clustering together isotopic profiles that are believed to be from the same isotopic signature eluting over a period of time. Each feature in the file has representative mass, elution time, drift time and charge state values that define the feature.
