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

so i used 3dvolreg as follows:

3dvolreg \
-zpad 4 \
-twopass \
-tshift 0 \
-prefix subject_EPI_Alnd_anat \
-base subject_anat+orig \
subject_EPI+orig

printed the following while processing:
++ Coarse del was 10, replace with 2

it didn't do a very good job though, its way off in the Z-axis, and slightly so in the x and y axes.

any other suggetions?

i also tried @SUMA_Align_To_Experiment (which uses the -twopass option of 3dvolreg, among others). This didn't work very well either. I have to think that being able to align an anat to extra-session anat is more difficult than aligning EPI to intra-session (but highly displaced) anat. Guess not.

Let me know. Thanks.
