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.
The +orig to +tlrc transformation is not one matrix, but is a set of 12 matrices, as specified in the Talairach and Tournoux book. (The fact that other programs use a single matrix is not my fault.) If you do want this information, it is available in the *+tlrc.HEAD file, in the WARP_DATA attribute. See the file README.attributes for more information.
