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

... and, since EPI is noisy, if you don't think there is much warping/stretching difference between the acquisitions and you are worried about fitting to noise (or, in this case, warping to noise) in the EPIs, you might also consider restricting the degrees of freedom of the affine fit. For example, you might think about using '-warp shift_rotate', so that your brain doesn't get stretched to fit noise in the skull or something.
