mne_rsa.compute_rdm#

mne_rsa.compute_rdm(data, metric='correlation', **kwargs)[source]#

Compute a dissimilarity matrix (RDM).

Parameters:

datandarray, shape (n_items, …): For each item, all the features. The first dimension are the items and all other dimensions will be flattened and treated as features.
metricstr | function: The distance metric to use to compute the RDM. Can be any metric supported by scipy.spatial.distance.pdist(). When a function is specified, it needs to take in two vectors and output a single number. See also the dist_params parameter to specify and additional parameter for the distance function. Defaults to ‘correlation’.
**kwargsdict, optional: Extra arguments for the distance metric. Refer to scipy.spatial.distance for a list of all other metrics and their arguments.

Returns:

rdmndarray, shape (n_classes * n_classes-1,): The RDM, in condensed form. See scipy.spatial.distance.squareform().
