I would like to enter a regressor that represents the neuronal activity (acquired with electrophysiology), therefore. a hemodynamic response function should be fitted to it.
It is a time series with the same duration as the fMRI scan consisting of continuous values.
I can't find a way to do it in 3dDeconvolve:
-stim_times is expecting onset times in seconds.
-stim_file would accept a time series, but does not get convolved with the response model, and neither does
-ortvec.
So is it the best option to manually convolve my regressor in matlab and then enter it as -stim_file? That's ok, but I would have liked to use one of the variable shape models in 3dDeconvolve.
