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 am working on learning to use Alphasim and I read through the .pdf file here: [afni.nimh.nih.gov]

I was a bit confused by 'Example 1. Uncorrelated Voxels' that goes from page 8 to page 10 in the .pdf file.

I thought I was understanding what Alphasim was doing but I am confused by the output statistics that list a Frequency of 331660 for a Cluster size of 1. How is it possible to get 331660 voxel clusters of size 1 from a dataset that has a total of 64x64x17=69632 voxels?
