Currently, when fitting the HRF, the grid stage for gauss is performed with the provided hrf initial parameters, and the grid stages for other models with fixed HRF parameters. it could be better to include the HRF parameter(s) directly within the grid stages, so that the grid output is not biased by the provided hrf initial parameters.
