Import in python using from mcutils.scripts.cifti.correlate import correlate_arr

mcutils.scripts.cifti.correlate.correlate_arr(arr1, arr2, collapse=False)[source]¶

Computes the Pearson r correlation for two arrays

Parameters

arr1 – (M, N) array for N observations of M variables
arr2 – (M, K) array for K obsevations of M variables
collapse – assume N==K and only return (N, ) array with the r correlation

Returns

(N, K) array with the r correlation (or (N, ) array if collapse is set)
