Hello,

Under glmSolveMethod is 1, which criteria of idxBasis 1 or 2 is better ?

“idxBasis=1” is realistic, I think.

Method of idxBasis=1 is same method as FIR Basis function ?

Consecutive sequence of gaussians function is used instead of boxcar(unit 1/sampling rate) ?

For HRF parameters of idxBasis=2, please provide the function to select best estimated "delay of response"  and "onset", such as "Uga,et al. Neurophotonics, Jul-Sep 2014 Vol.1(1)" , to give the maximum beta value.

Best regards,

At Boston University Meryem Yücel and I have always liked using idxBasis=1 since this does not impose an assumption for the shape of the HRF. It only imposes a smoothness assumption which the user can control with the parameters for this choice of basis function.
