Hi,

I'm trying to get a cluster report from 3dclust that includes the center of mass, coordinates of peak value, etc. When I run 3dclust on a particular seed region, I get a report of the stats for 1 big cluster (within which are multiple smaller patches) that spans pretty much the whole brain. Then, when I use the -erode and -dilate features with 3dmerge, it breaks up the big cluster into 4 smaller ones, which is good.

I am able to get a read-out of the % overlap of all Talairach regions that fall within clusters from the 3dmerge-edited dataset (with the new command line program 'whereami'). However, when I run 3dclust on the 3dmerge-edited data, I get a cluster report of 3 instead of 4 clusters, but I would like to get it on the original 4, because that is what the % overlap information is based on.

How do I do that?

Thanks,

Liam
