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

I have used 3dROIstats to compute the number of non-zero voxels contained within a region-of-interest mask. I am wondering if there is a way to further compute the number of non-zero voxels within this mask that exceed a given size parameter (e.g., 1 mL contiguous). In other words, I would like to compute the number of non-zero voxels only if there are a total of approx. 296 adjoining voxels (at 1.5 isotropic resolution this would equate approx. 1mL contiguous).

Thanks in advance for your input.

Best,
Jesse
