pyntbci.stimulus.is_de_bruijn_sequence

pyntbci.stimulus.is_de_bruijn_sequence(stimulus: ndarray[Any, dtype[_ScalarType_co]], k: int = 2, n: int = 6) → bool

Check whether a stimulus is a de Bruijn sequence. A de Bruijn sequence [1] should contain all possible substrings of the alphabet.

Parameters:

• stimulus (NDArray) – A vector with the de Bruijn sequence of shape (1, n_bits).

• k (int (default: 2)) – The size of the alphabet.

• n (int (default: 6)) – The order of the sequence.

Returns:

out – True if the stimulus is a de Bruijn sequence, otherwise False.

Return type:

bool
