Dear AFNI users-

We are very pleased to announce that the new AFNI Message Board framework is up! Please join us at:

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

Dear Colleagues

I have an absolute beginner question (I`ve just installed AFNI for the first time...):

how to run the 3dClustSim to determine the cluster size threshold for 2nd level contrasts? Results come from an ICA analysis in GIFT (spatial maps), preprocessing was done with SPM12. Most importantly: what is the INPUT for both 3dFWHMx and 3dClustSim? Is it an actual t-contrast image (e.g. thresholded at 0.05 uncorrected)?

I read previous messages, but still I`m very unsure how to do that.

Your answer is much appreciated.
Lucas
