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.
This error message means you have a .HEAD file but no corresponding .BRIK (or .BRIK.gz) file. This is legal, but only if the BRIK-less .HEAD file contains inside a "warp" (coordinate transformation) that indicates another dataset from which it can get data. If you have a BRIK-less file that also does not have this "warp" information inside, you get this message -- AFNI doesn't know where to get the data for display.
