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?
