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 warning is there because the dataset names/labels will also be used when looking up covariates; that is, if you used the '-covariates' option. If that were the case, the '-covariates' option would be very unhappy with you (since it would be unable to tell which line in the covariates table went with which input dataset). Otherwise, what you got is just a warning message -- in case you might want to add covariates at a later date.
