tensorpac.utils.pac_vec(f_pha='mres', f_amp='mres')

Generate cross-frequency coupling vectors.

Parameters

Frequency vector for the phase and amplitude. Here you can use

several forms to define those vectors :

• Basic list/tuple (ex: [2, 4] or [8, 12]…)

• List of frequency bands (ex: [[2, 4], [5, 7]]…)

• Dynamic definition : (start, stop, width, step)

• Range definition (ex : np.arange(3) => [[0, 1], [1, 2]])

• Using a string. f_pha and f_amp can be ‘lres’, ‘mres’, ‘hres’ respectively for low, middle and high resolution vectors. In that case, it uses the definition proposed by Bahramisharif et al. 2013 [2] i.e f_pha = [f - f / 4, f + f / 4] and f_amp = [f - f / 8, f + f / 8]

Returns

f_pha, f_amparray_like

Arrays containing the pairs of phase and amplitude frequencies. Each vector have a shape of (N, 2).
