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 Dan,
I tried -zpad from 20 to 100 in increments of 10. The cut corners gradually come back with increasing -zpad. Turned out that I need a minimum of 70 to completely recover the corners.

I also tried -cubic and other interpolations but those also need a zpad of 70.

One thing I failed to mention thinking it to be not important is that the dimensions of the volume are 192x192x8 voxels (as these are images of the spine). I am rotating in the 192x192 plane so I thought that the depth-dimension didn't matter. Could that be the reason why I need so much padding?
