Module Description

This module is used for selecting a subset of DTI fiber tracts including or excluding certain fibers passing through a selected set of labels in the label map volume.

Use Cases

Most frequently used for these scenarios:

  • Use Case 1: Filter out a subset of DTI fiber tracts which are passing through selected region(s) defined in the label map volume.
  • Use Case 2: Filter out a subset of DTI fiber tracts which are NOT passing through selected region(s) defined in the label map volume.
  • Use Case 3: A combination of Case 1 and Case 2.
