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 Rick, Thanks for responding so quickly! The data is from humans and was collected on a 3T scanner. Moreover, I have analyzed this exact dataset before using 3dttest++ and -Clustsim. The only difference is that with the original analyses I warped the data to TLRC using AFNI but this time I warped it with ANTS. So I assume it is some issue caused by the ANTS warping. I noticed that the grid spacing for the ANTS warped data is 1x1x1 and the grid spacing for the original AFNI warped data is 2.2x2.2x2.2 (which is the same size as the raw data). Could this be the cause of the issue? If so, it seems like it could be easily fixed by resampling the ANTS warped data to say 2x2x2, right?

Thank you again!
Regan
