tedana.metrics.dependence.compute_dice

compute_dice(*, clmaps1: ndarray, clmaps2: ndarray, axis: int | None = 0) → ndarray[source]

Compute the Dice similarity index between two thresholded and binarized maps.

NaNs are converted automatically to zeroes.

Parameters:

clmaps1, clmaps2 ((S x C) array_like) – Thresholded and binarized arrays.
axis (int or None, optional) – Axis along which to calculate DSI. Default is 0.

Returns:

dice_values (array_like) – DSI values.
