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 Josh,

In afni_proc.py, assuming the EPI data is resampled
(because of alignment to the anat or transformation
to standard space), the voxel resolution applied will
default to isotropic voxels of the minimum original
dimension, truncated to 3 significant bits (so 3.75
is truncated to 3.5).

Resampling ahead of time would blur the data and
destroy any slice timing. There is no reason to do
so.

Please see '-volreg_warp_dxyz DXYZ' in the -help
output:

afni_proc.py -help
