Get Run Lengths from Sampling Frame

Extracts the lengths of individual runs/blocks from objects containing temporal structure information.

Usage

get_run_lengths(x, ...)

# S3 method for class 'matrix_dataset'
get_run_lengths(x, ...)

# S3 method for class 'fmri_dataset'
get_run_lengths(x, ...)

# S3 method for class 'fmri_mem_dataset'
get_run_lengths(x, ...)

# S3 method for class 'fmri_file_dataset'
get_run_lengths(x, ...)

# S3 method for class 'fmri_study_dataset'
get_run_lengths(x, ...)

# S3 method for class 'sampling_frame'
get_run_lengths(x, ...)

Arguments

x

An object containing temporal structure (e.g., sampling_frame, fmri_dataset)

...

Additional arguments passed to methods

Value

Integer vector where each element represents the number of timepoints in the corresponding run

Details

This function is synonymous with blocklens but uses terminology more common in fMRI analysis. Each run represents a continuous acquisition period, and the run length is the number of timepoints (volumes) in that run.

See also

blocklens for equivalent function, n_runs for number of runs, n_timepoints for total timepoints

Examples

# \donttest{
# Create a sampling frame with 3 runs
sf <- fmrihrf::sampling_frame(blocklens = c(100, 120, 110), TR = 2)
get_run_lengths(sf) # Returns: c(100, 120, 110)
#> [1] 100 120 110
# }
