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,

I'm having trouble getting 3dmerge to work with the option:

-1clust rmm vmul

where I've tried lot's of different values for rmm vmul.

The ouput is always the same as the input (for each sub-briks).

specifically here is an example command:
3dmerge -prefix cluster -doall -1clust 0 66.9672 epi_stats+orig

where 66.9672=12*5.806
and 5.806=sqrt(voxdim1_mm^2 + voxdim2_mm^2 + voxdim3_mm^2)
and 12 is the minimum cluster size threshold output by AlphaSim.

Should this work (or at least give me output different from input)?
