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

Hello. I work with mouse fMRI. After normalizing my functional images with SPM, I am able to see that my normalized results after 3ddeconvolve or 3dttest++, the areas align well with the template crosshair (when opened in new AFNI window) However, I want to be able to align my template ROIs over my functional results instead of using photoshop to try align it properly. I asked before how to resample and got the suggestions to use 3dresample, 3dNwarpApply, or 3dfractionize, but I ran into either errors about template space, or the template ROI lines becoming too undersampled. Here are the 3dinfo for my template and functional scans. My template is in ORIG space, but normalized functional scans in TLRC. I've also attached the results of 3dresample. I've tried multiple rmodes and get similar results. Even after 3dresample, I am unable to use the resampled template as my underlay for my 3dttest overlay.
