I think these images come from the post-cluster-thresholded statistics. Perhaps you're mistaking an activation region which is part of an existing cluster for a discrete cluster? You could check against the cluster mask to make sure.

Hello list!
When visually inspecting a rendered_threshold_zstat image in fslview, I noticed some clusters with intensities like 3.5 and 3.9 that aren't listed in the cluster browser.
Does this means that they're not statistically relevant?

Thanks in advance.
