sjd.demo {fsbrain}

Download optional demo data if needed and return its path.

Description

This is a wrapper around download_optional_data() and get_optional_data_filepath("subjects_dir"). It will download the optional fsbrain demo data unless it already exists locally.

Usage

sjd.demo(accept_freesurfer_license = FALSE)

Arguments

accept_freesurfer_license

logical, whether you want to also download fsaverage and fsaverage3, and accept the FreeSurfer license for fsaverage and fsaverage3, available at https://surfer.nmr.mgh.harvard.edu/fswiki/FreeSurferSoftwareLicense. Defaults to FALSE. If FALSE, only the demo data from fsbrain itself ('subject1') will be downloaded.

Value

character string, the path to the 'subjects_dir' directory within the downloaded optional data directory.

Note

This function will stop if the data cannot be accessed, i.e., the 'subjects_dir' does not exist after trying to download the data.
