Get Data from fMRI Dataset Objects

Generic function to extract data from various fMRI dataset types. Returns the underlying data in its native format (NeuroVec, matrix, etc.).

Usage

get_data(x, ...)

Arguments

x

An fMRI dataset object (e.g., fmri_dataset, matrix_dataset)

...

Additional arguments passed to methods

Value

Dataset-specific data object:

• For fmri_dataset: Returns the underlying NeuroVec or matrix

• For matrix_dataset: Returns the data matrix

Details

This function extracts the raw data from dataset objects, preserving the original data type. For NeuroVec-based datasets, returns a NeuroVec object. For matrix-based datasets, returns a matrix.

get_data_matrix for extracting data as a matrix, get_mask for extracting the mask

Examples

# \donttest{
# Create a matrix dataset
mat <- matrix(rnorm(100 * 50), nrow = 100, ncol = 50)
ds <- matrix_dataset(mat, TR = 2, run_length = 100)

# Extract the data
data <- get_data(ds)
identical(data, mat) # TRUE
#> [1] TRUE
# }
