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

It's a little more complicated than that. The dataset is stored with a scale factor as bytes, and each ROI sub-brick has a different scale factor. Use this method instead to extract the region.

3dcalc -a $HOME/abin//TT_desai_ddpmaps+tlrc'[ctx_lh_G_insular_short]' -prefix insular_short -float -overwrite -expr 'step(a-0.3)'

3drefit -denote insular_short+tlrc.

That particular atlas has a very long history in the header, so I just trimmed it away with the 3drefit command.
