Hi,
While entering my own design matrix, containing regressors of interest and non-interest in SPM using the entry "multiple regressors" in the batch (model specification) I obtain results that are partially different than what SPM would have produce if the regressors would have been input in the standard way. Would it be possible to know exactly all the SPM steps in this part of the analysis (e.g. the hrf function used, how the stimuli function is created, how regressors are created, demeaned and orthogonolized..).
Thanks a lot,
Elsa
