create_design_matrix_from_benchmark: Create Design Matrix from Benchmark Dataset

In bbuchsbaum/fmrireg: R package for the anlysis of fmri data

Create Design Matrix from Benchmark Dataset

Description

Helper function to create a design matrix from a benchmark dataset using a specified HRF. This is useful for testing different HRF assumptions against the ground truth.

Usage

create_design_matrix_from_benchmark(
  dataset_name,
  hrf,
  include_intercept = TRUE
)

Arguments

dataset_name	Character string specifying which dataset to use
hrf	HRF object to use for convolution (e.g., fmrihrf::HRF_SPMG1)
include_intercept	Logical, whether to include an intercept column

Value

A matrix with the design matrix (time x conditions)

Examples

# Create design matrix using canonical HRF
X <- create_design_matrix_from_benchmark("BM_Canonical_HighSNR", fmrihrf::HRF_SPMG1)

# Test with a different HRF
X_wrong <- create_design_matrix_from_benchmark("BM_Canonical_HighSNR", fmrihrf::HRF_SPMG2)
