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.
Are you using the AFNI_TTATLAS_DATASET variable
somewhere (in your shell or your .afnirc file)?
Otherwise it then checks AFNI_PLUGINPATH before your
PATH directories.
It seems likely that you have one of those set to a
directory without the dataset (or with an old version).
Current versions of the atlases come with the binaries.
