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.
That covariate file has a column of nan's. It would be worth removing that and seeing if it helps (as it should not be useful in the regression anyway).
Do you have any of the screen text that appears just before the crash? That might make the context more clear. You can also run 'top' while this is going, and track memory usage against how much you have.
