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 Shantanu,
Christine is right, but I'd also like to mention that you can use the option -dxyz=1 to artificially set all the voxels to 1x1x1, in case that's simpler.
Here's a quote from the documentation for 3dclust:
If you use -dxyz=1, then rmm should be given in terms of
voxel edges (not mm) and vmul should be given in terms of
voxel counts (not microliters). Thus, to connect to only
3D nearest neighbors and keep clusters of 10 voxels or more,
use something like '3dclust -dxyz=1 1.01 10 dset+orig'.
In the report, 'Volume' will be voxel count, but the rest of
the coordinate dependent information will be in actual xyz
millimeters.

Sally
