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 am doing a bit of pre-processing on functional fMRI images using Nipype-AFNI and I always get a warning saying " oblique dataset is ... degrees away from the plumb, consider using 3DWarp", but when I do use the 3dWarp command on my functional scans, the dimensions of the resulting fMRI image is different from the original. For instance my original data has the dimensions - 64*64*33*150 but after 3dWarp I get 64*73*56*150. Is this normal? ( I am relatively new to the world of fMRI, please do feel free to correct me, if my basic concepts are wrong.)

Thank You.
