AFNI HRF Constructor Function

Description

The AFNI_HRF function creates an object representing an AFNI-specific hemodynamic response function (HRF). It is a class constructor for AFNI HRFs.

Usage

AFNI_HRF(name, nbasis, params)

HRF_GAUSSIAN(t, mean = 6, sd = 2)

HRF_BSPLINE(t, span = 20, N = 5, degree = 3)

HRF_SPMG1(t, P1 = 5, P2 = 15, A1 = 0.0833)

HRF_SPMG2(t)

HRF_SPMG3(t)

Arguments

name	A string specifying the name of the AFNI HRF.
nbasis	An integer representing the number of basis functions for the AFNI HRF.
params	A list containing the parameter values for the AFNI HRF.
span	A numeric value representing the span in seconds of the HRF. Default is 24.

Value

An AFNI_HRF object with the specified properties.

Functions

• AFNI_HRF(): AFNI hrf

• HRF_GAUSSIAN(): Gaussian hrf

• HRF_BSPLINE(): B-spline hrf

• HRF_SPMG1(): SPMG1 hrf
