Hi Laetitia,

the general output of the family of functions that you mentioned is as

T_obs (unthresholded statistical map), clusters (the clusters), cluster_pv
(the cluster level p-value), H0 (the maximum cluster size / cluster stat).

the indices in `clusters` refer to the spatial and temporal locations.

In this example you can see how to make use of this information (at the


I hope this helps,
