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 David,

What leaps out is using over 8 GB of RAM. How much RAM do you have?
If it cannot support that, your computer would probably start thrashing
(continually reading and writing swap memory), and it could take a very
long time to complete the process.

If you have enough RAM, then Peter's suggestion for CPU use is great.

If you are on the edge of memory, add the -regress_compute_fitts option
to afni_proc.py. That would drop the RAM usage in 3dDeconvolve by
computing that dataset after the fact (using all_runs and errts). So
it might save ~30% of the RAM usage.

Are you working with high-resolution EPI data?
Exactly how much RAM do you have?
Did you use the -volreg_warp_dxyz option?
