Webnumpy.unravel_index# numpy. unravel_index (indices, shape, order = 'C') # Converts a flat index or array of flat indices into a tuple of coordinate arrays. Parameters: indices array_like. An integer array whose elements are indices into the flattened version of an array of dimensions shape.Before version 1.6.0, this function accepted just one index value. WebHere we have a 4D array from an FMRI run ( ds114_sub009_t2r1.nii ): To get the number of voxels in the volume, we can use the np.prod function on the shape. np.prod is like np.sum, but instead of adding the elements, it multiplies them: Then we can reshape the array to 2D, with voxels on the first axis, and time (volume) on the second. cctc courthouse
