compute_countnoise(stat_maps, stat_cl_maps, stat_thresh=1.95)[source]

Count the number of significant voxels from non-significant clusters.

This is done after application of a cluster-defining threshold, but compared against results from cluster-extent thresholding.

Parameters:

  • stat_maps ((S x C) array_like) – Unthresholded statistical maps.

  • stat_cl_maps ((S x C) array_like) – Cluster-extent thresholded and binarized version of stat_maps.

  • stat_thresh (float, optional) – Statistical threshold. Default is 1.95 (Z-statistic threshold corresponding to p<X one-sided).

Returns:

countnoise ((C) array_like) – Numbers of significant non-cluster voxels from the statistical maps.
