WebCommand Structure. The exact command to run in xcp_d depends on the Installation_ method and data that needs to be processed. We start first with the the bare-metal :ref:`Manually Prepared Environment (Python 3.8+)` installation, as the command line is simpler. xcp_d can be executed on the command line, processesing fMRIPrep outputs, … WebRather than the whole response at one voxel, we may prefer just one parameter, the delay, estimated at all voxels. Delays are shifts of the time origin of the HRF, measured in seconds. CONTRAST_IS_DELAY is a logical vector indicating if the row of CONTRAST is a contrast in the delays (1) or magnitudes (0).

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 WebIn this case we will get an HRF regressor and a TD regressor. Next we multiply the betas that we have by the regressors (HRF beta * HRF regressor, TD beta * TD regressor), …
