Dear FSL experts
I conducted a vertex-wise shape analysis with FIRST, following the user guide. I ran first_utils and then randomise by choosing the TFCE option. After randomise I ran the cluster command to extract cluster information. Because the shape analysis is vertex-based, I wonder how the randomise and cluster commands (which are voxel-based) have to be interpreted. For example: When running the cluster command revealing a cluster of 139 voxels, does the number of voxels correspond to the number of vertices?
Thank you for your help.
Best regards
Dorian Bellwald
