Hi Everyone,
I’m using PyMVPA’s fit_event_hrf_model to fit a GLM for two regressors that I’ve fed
into “events”, which get convolved with HRF. I however want to add a column
to my design matrix to include GSR, which is now stored as a sample
attribute in my dataset. But how can I do that, so that the specific column
for GSR doesn’t get convolved with HRF? My best guess now is using the
“regr_attrs” parameter of fit_event_hrf_model and specifying the GSR sample
attribute will do this for me; and what’s given to “regr_attrs” is not
going to go under convolution with HRF. Is that true? Any other
suggestions? Thanks a lot!
