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

You could do this with your original EPI datasets:

3dcalc -a epi_r1+orig -expr t -prefix tt_epi_time

This replaces every voxel with the time it was acquired because 't' is a reserved variable for that purpose in 3dcalc. Then you could just apply the same warping to cardinal with 3dWarp on that time dataset. There is the question of what to do with interpolation there. It may be most appropriate to use Nearest Neighbor interpolation rather than computing an interpolated value.
