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 Siamak,

The basic question is whether these voxels are actually in
the same location in space. Do the origins or extents (as
reported by 3dinfo) differ by 1mm on one side, or by 0.5mm
on each side (in each of the 3 directions)?

If you are not sure what I mean, please post the output of
3dinfo on each dataset.

If the voxels are in the same positions (meaning you just
need to add or remove one slice), then there will be no
resampling involved. Otherwise, there will.

In any case, 3dresample will work fine:

3dresample -master GOAL_GRID+orig -input SOURCE_GRID+orig \
-prefix SOURCE_AT_GOAL
