Hi there!
Looking for clarification on significance estimates for individual clusters in the clusterize gui.
I notice that some clusters have a p-value inequality with two <<, and others have just one <
What is the difference between p <<.01 and p <.01 ? How should we be reporting the corrected significance of these clusters?
For instance see the url link to this image
:
Cluster Table
The table says that over 98 voxels has a threshold of p : .01. In my case, clusters with anywhere between 200 (cluster 4) and 4000 (cluster 1) voxels have an indicated p value of p<<.01. But I would expect the 200 voxel cluster with a reported p <<.01 would be more similar in significance to a cluster of 140 voxels (cluster 5) with p <.01, rather than a cluster of 4000!
Thanks in advance for the help!
