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

To clarify further, consider two parallel runs of align_epi_anat with different deoblique options. The result is always plumb.

align_epi_anat -deoblique off -anat T1 -epi b0........ -> Plumb_T1_al + inv_mat_1

align_epi_anat -deoblique on -anat T1 -epi b0..........-> Plumb_T1_al + inv_mat_2

Is inv_mat_1 = inv_mat_2??

If not, when I attempt a reverse alignment using 3dallineate, while using which inv_mat (1 or 2) should I precede it with an additional obliquing/deobliquing step?

Hope this makes sense!
