Group Regions Filtering

Simplifies the group profile with an implementation of watershed algorithm.

Description

Usage example

normed_group_profile:           /my/path/brainvisa_db/subjects/group_analysis/g1/connectivity_clustering/avg/initiation/lh.inferiorparietal/smooth3.0

reduced_group_profile: Connectivity ROI Texture ( output )

Group profile after watershed computing.

filtered_reduced_group_profile: Connectivity ROI Texture ( output )

Group profile after watershed computing and elimination of low connectivity basins.
