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

Neither MNI nor Talairach space is not one specific space, but each corresponds to a kind of family of spaces. MNI has about a dozen popular variants. The Desai atlases were made using AFNI's @auto_tlrc function by alignment to the TT_N27 space. Consequently, the atlas is the TT_N27 variant of Talairach space.

Consider the following options to transform data or coordinates between MNI and Talairach spaces :
1. Affine, 2-piece affine and 12-piece affine transformations to go from generic Talairach to generic MNI.
[afni.nimh.nih.gov]
[afni.nimh.nih.gov]
2. 12-piece affine to go from TT_N27 to MNI_N27, and MNI_N27 to TT_N27.
[afni.nimh.nih.gov]
[afni.nimh.nih.gov] (same as in #1)
3. Affine+nonlinear warp to go from TT_N27 to MNI_2009c

4. Use FreeSurfer parcellations for MNI_2009c instead of Desai atlases. See aparc+aseg+REN_all.nii.gz in compressed file below.
