You can get the center of the mass with fslstats -c (or -C).

Subject: [FSL] locating cluster's center of activation
Hello fsl-users,
After VBM analysis with fsl, quite big clusters of difference among my
groups were found. Calculating the center of mass for each cluster to locate
"the activation center" of each cluster can give good results only when
clusters have an appropriate shape. Iterative erosions of a cluster is
another way of finding the cluster's activation center but developing in
house code for such usage will result in a subjective localization of
cluster's " activation center" that won't be reproducible elsewhere but my
computer. Do you know if there is any fsl utility that can cope with this
issue and locate a cluster's center from the
fslvbm_clustere_corrp_tstat1.nii.gz and fslvbm_clusterm_corrp_tstat1.nii.gz
files? If there's no fsl utility for this, do you know any other wide used
software/utility that can do this task?
Thank you again
Antonios-Konstantinos
