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 AFNI experts,

I have used 3dAllineate to transform an MNI template to a participant's diffusion space (their FA image). I then use this transformation to warp an ROI (originally in MNI space) to the participant's diffusion space. Unfortunately, the corpus collusum is slightly misaligned on my first transformation, so this affects my ACC ROI registration. I used nearest neighbor interpolation.

Are there any othe tricks I can try before resorting to non-linear warp?

Thanks,

Emily
