pyntbci.stimulus.make_de_bruijn_sequence

pyntbci.stimulus.make_de_bruijn_sequence(k: int = 2, n: int = 6, seed: list[int] = None) → NDArray

Make a de Bruijn sequence. This code to generate a de Bruijn sequence is largely inspired by Eviatar Bach.

Parameters:

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

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

• seed (list[int] (default: None)) – Seed for the initial register. None leads to an all zero initial register.

Returns:

stimulus – A matrix with a de Bruijn sequence of shape (1, n_bits).

Return type:

NDArray
