nilearn.glm.first_level.glover_time_derivative

nilearn.glm.first_level.glover_time_derivative(tr, oversampling=50, time_length=32.0, onset=0.0)

Implement the Glover time derivative HRF (dhrf) model.

Parameters:

trfloat

Repetition time, in seconds (sampling period).

oversamplingint, default=50

Temporal oversampling factor.

time_lengthfloat, default=32

HRF kernel length, in seconds.

onsetfloat, default=0

Onset of the response.

Returns:

dhrfarray of shape(length / tr), dtype=float

dhrf sampling on the provided grid
