hrf_convolve_normalize: convolve a regressor with a normalized HRF with peak...

Description Usage

Description

extends fmri.stimulus by allowing for two normalization approaches (building on AFNI dmUBLOCK): 1) pre-convolution HRF max=1.0 normalization of each stimulus regardless of duration: identical to dmUBLOCK(1) 2) pre-convolution HRF max=1.0 normalization for long events (15+ sec) – height of HRF is modulated by duration of event: identical to dmUBLOCK(0)
