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

Hi Matt,

Would you mind posting a sample of one of the timing files that is not giving you the number of betas that you expect? Or, you could mail me the timing file along with any X.xmat.1D file (or a nocensor version).

Are you using afni_proc.py? If so, try adding -regress_compute_fitts. That will use 3dcalc to compute the fitts, rather than having 3dDeconvolve (use the extra RAM to compute and) write it out.

While 16 GB seems like plenty for this, if other programs (like web browsers) are using all of the RAM, you might have to close some programs.
