Temporal information in spatio-temporal clustering

Dear list members,

I did spatio-temporal clustering on my source data, following the example "
Permutation t-test on source data with spatio-temporal clustering", based
on the function spatio_temporal_cluster_1samp_test. I saved the stc file
containing my significant clusters, but I couldn't manage to retrieve
temporal information about the clusters. If I understand well, the color
value corresponds to the significant duration of one source in the cluster
but we don't know at which time the cluster begins. What did I miss ?...

Thanks in advance,
Laetitia

Hi Laetitia,

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

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
bottom):

I hope this helps,
best,
Denis
