AFNI Message Board

Dear AFNI users-

We are very pleased to announce that the new AFNI Message Board framework is up! Please join us at:

https://discuss.afni.nimh.nih.gov

Existing user accounts have been migrated, so returning users can login by requesting a password reset. New users can create accounts, as well, through a standard account creation process. Please note that these setup emails might initially go to spam folders (esp. for NIH users!), so please check those locations in the beginning.

The current Message Board discussion threads have been migrated to the new framework. The current Message Board will remain visible, but read-only, for a little while.

Sincerely, AFNI HQ

Hi afni users,

In my study, I have 26 subjects, each with values for three different conditions (cond1, cond2, cond3). Based on previous data, I would expect there to be certain brain regions that show increased activity for cond1 relative to both cond2 and cond3 (with no difference in activity between those two), certain brain regions that show decreased activity for cond3 relative to cond1 and cond2 (with no difference between those two), and certain regions showing a linear increase between the three conditions. In summary:

cond1 > cond2 = cond3
cond1 = cond2 > cond3
cond1 > cond2 > cond3

What is the best way to analyze the data in order to isolate regions of brain activity that satisfy each of these conditions?

Thanks,
Jena
