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

I have run 3dGCR now for several subjects/ROI combinations. For every single one, I get data for the path coefficients, but there is no data in the t-stats brik--for either the seed-to-target or the self-effect. However, the data looks as it should for the target-to-seed (with data in both briks, including t).

Have you run into this problem before? Do you know what could be going wrong? It is confusing to me that there would be t-stats for the target-to-seed, but not for the seed-to-target.

I can upload some the input and output briks if you want to look at them.
