Hi Doug,
Since our external regressors are stimulus-related (e.g. mean luminance of stimuli), we need to convolve them with a hemodynamic response function. In mkanalysis-sess, we have used -spmhrf 0 to model conditions. Is there a code or Matlab script for HRF convolution, so that we apply exactly the same spmhrf function for modeling the external regressors?
Thanks, Reza
No, they are not
