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

The error is most likely due to the problem of statistics toolbox in Matlab. Type

which grp2idx

inside Matlab. If it does not know it, you don't have the statistics toolbox for the 2007b version, and you have to pay Mathworks some extra money to update the toolbox. Or you can try the old version if it's still available on your machine.

Another option is to use 3dLME.R
