mvpa2.misc.data_generators.double_gamma_hrf(t, A1=5.4, W1=5.2, K1=1.0, A2=10.8, W2=7.35, K2=0.35)

Hemodynamic response function model.

The version is using two gamma functions (also see single_gamma_hrf()).

Parameters:

t : float

Time.

A : float

Time to peak.

W : float

Full-width at half-maximum.

K : float

Scaling factor.

Parameters A, W and K exists individually for each of both gamma

functions.
