Create B-spline HRF Basis Set

Generates an HRF object using B-spline basis functions with custom parameters. This is the generator function that creates HRF objects with variable numbers of basis functions, unlike the pre-defined HRF_BSPLINE which has 5 functions.

Usage

hrf_bspline_generator(nbasis = 5, span = 24)

Arguments

nbasis

Number of basis functions (default: 5)

span

Temporal window in seconds (default: 24)

Value

An HRF object of class c("BSpline_HRF", "HRF", "function")

HRF_objects for pre-defined HRF objects, getHRF for a unified interface to create HRFs

Examples

# Create B-spline basis with 10 functions
custom_bs <- hrf_bspline_generator(nbasis = 10)
#> Warning: Parameters nbasis, degree, span are not arguments to function bspline and will be ignored
t <- seq(0, 24, by = 0.1)
response <- evaluate(custom_bs, t)
matplot(t, response, type = "l", main = "B-spline HRF with 10 basis functions")
