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 Tamara,

(1) The 15-30 mm value depends on the voxel size and the mask.
It does not use a fixed size. I expect that your voxels are
a bit small. How big are they? Did you use a 4-5 mm blur?

Those values look fine.

(2) Yes, you should make a group mask to apply and run 3dClustSim
with. Perhaps make an intersection or 70% overlap mask of all of
the subject full_mask or mask_epi_anat datasets to use for the
group mask.

Consider the commands in this example of a full analysis:

AFNI_demos/AFNI_pamenc/AFNI_02_pamenc/global_process_commands.txt

There is also a related global_process_outline.txt file there.

Does that seem reasonable?

- rick
