You can use -cifti-find-clusters if you just want spatial contiguity to
define where ROIs should be considered separate, then use
-cifti-label-import to make them into a dlabel file.

A single coordinate isn't a faithful representation of the cluster. You
can make a figure showing the clusters displayed on the brain (for
instance, choose two of: beta maps, significance outlines, area outlines),
and hopefully also provide the unthresholded beta and z maps for others to
You can get cluster extent info with -cifti-weighted-stats.
If the question you want to ask is "which areas are involved", you could do
a parcellated analysis instead of a cluster analysis.
