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

Hello,

I ran a paired t-test using 3dttest++ with the -ETAC flag. The results in the {PREFIX}.{NAME}.ETACmask.global.{SIDE}.{FPR}.nii.gz file look great. This may be a fundamental misunderstanding on my part of ETAC, but is there any way to isolate anatomical regions into clusters from this binarized map? For example, with cluststim parameters I can threshold and then run 3dclusterize to obtain an ordered cluster map.

Is {PREFIX}.{NAME}.ETACmask.global.{SIDE}.{FPR}.nii.gz the "final" map and would I report the entire map as "one cluster" in a manuscript?

Thank you,
Cate
