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 was trying to play with ETAC today. I ran a two group 3dTtest++ with -ETAC on seed-based resting state data. I had done the preprocessing with a 6mm blur so I didn't use the -ETAC_blur option.

For the results output, I am unclear if I should set the threshold bar to 0.05 or if I should set the threshold bar to a lower value, like 0.002.
For example, how should I interpret a "significant" cluster at per-voxel p= 0.05 with a voxel size of 10, with 3.5 mm isotropic voxels?
