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

Create a Matrix Dataset Object

Description

This function creates a matrix dataset object, which is a list containing information about the data matrix, TR, number of runs, event table, sampling frame, and mask.

Usage

matrix_dataset(datamat, TR, run_length, event_table = data.frame())

Arguments

datamat	A matrix where each column is a voxel time-series.
TR	Repetition time (TR) of the fMRI acquisition.
run_length	A numeric vector specifying the length of each run in the dataset.
event_table	An optional data frame containing event information. Default is an empty data frame.

Value

A matrix dataset object of class c("matrix_dataset", "fmri_dataset", "list").

Examples

# A matrix with 100 rows and 100 columns (voxels)
X <- matrix(rnorm(100*100), 100, 100)
dset <- matrix_dataset(X, TR=2, run_length=100)
