Value

A ProcessingSettings S3 class object with subclass MassSpecSettings_FilterFeatures_patRoon.

Details

Note that when filters are applied to features or feature groups these require specific results from processing modules. For instance, subtracting the blank can only be done after grouping features. Also, some filters require. Thus, not all filters can be applied to features. See features-class and replicateGroupSubtract for further information.
