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 my task, but I haven't found any documentation on how to do this or even if it is possible with the current commands. I'm thinking of trying to use a tpexclude file and excluding all time points except Condition A and running functional connectivity on just those time points. And then making a separate tpexclude file that excludes all of the time points except those in Condition B and running functional connectivity on that (both with hippocampal seeds). This would give me maps for each condition. Is there a standard statistical test to compare one map to another? This seems to be a work-around, so I'm curious if anyone has a better solution to do task-related functional connectivity in Freesurfer 5.
Please let me know if you've done this or know how to!
Thanks!
Maya
