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

Heather,

Option GOFORIT is only a band-aid. The fundamental question is, why do you have the collinearity problem? Is it because of some identical regressors (by mistake) or something else? If you're not so sure, add option -x1D so that you can use program such as ExamineXmat or xmat_tool.py to check the design matrix.
