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

If your data is in Talairach space, and you want to use an MNI atlas, then you have a few choices:

1. Redo the analysis in MNI. This is the most accurate generally, assuming you know which MNI template to use for that atlas.
2. Move the atlas to Talairach space.
3. Move your statistical results or statistical coordinate to MNI space.

Both of the last two choices, require transforming the data between MNI and Talairach spaces. That can be accomplished several ways. If your data was put into Talairach space by alignment to the TT_N27 dataset, then you can use an exact 12-piece transformation. See these previous post and its included links for how to do that.

For the SUIT Cerebellum atlas, there is an AFNI version of that here. Since then, there have been some updates too including the most recent functional atlas that can be used too.
