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

I tried this a couple months ago for generic ROIs:

[afni.nimh.nih.gov]

For hemispheres, I just tried this with success:

@auto_tlrc -base TT_N27+tlrc -suffix None -input anat+orig
3dcalc -a anat+tlrc -expr 'a*ispositive(x)' -prefix lefthemi
3dcalc -a anat+tlrc -expr 'a*(iszero(ispositive(x)))' -prefix righthemi
3dLRflip -prefix righthemi_flip righthemi+tlrc.
3dAllineate -cmass -warp shift_rotate -base lefthemi+tlrc. \
-source righthemi_flip+tlrc. -prefix righthemi_flip_al2left \
-cost ls -source_mask lefthemi+tlrc -weight lefthemi+tlrc.

The tlrc dataset was created using the @auto_tlrc script. The aligned hemispheres are attached in a jpeg image.
