"Webput is given as a time series of image volumes, containing the HRF at each voxel loc-ation. Compared to other HRF extraction methods (Glover 1999, Miezin et al. 2000), the method requires only a few assumptions: the stimulus-response relation should be linear and time invariant (LTI), and the signal should be distinguishable from noise in " - Hrf time
