Dear Freesurfers, I'm really glad to see the (relatively) new functional connectivity commands. It seems to be working really well. Has anyone tried to do task-related functional connectivity? I would like to compare functional connectivity with the hippocampus during two different conditions of

[Freesurfer] 5.1.0 volume analysis in native space
