what do you mean "extract" the cluster? Do you want mean thickness for each cluster? Or the mean contrast? Of all the voxels in a cluster? For the first two, you can use something like
mri_segstats --seg clusterseg.mgz --i contrast.mgz --sum summary.txt

External Email - Use Caution

Hi,

I ran a longitudinal two stage model analysis in 83 participants comparing two groups. After applying cluster correction, I am seeing several significant regions, and I was wondering if there is a way to extract each significant cluster from each participant.

I appreciate any help!

Thank you,

Liliana
