Download the FreeSurfer v6 low-resolution fsaverage3 subject.
Description
Download some relevant files from the FreeSurfer v6 fsaverage3 subject. The files are subject to the FreeSurfer software license, see parameter 'accept_freesurfer_license' for details. This data is not required for the package to work. If you are working on a machine that has FreeSurfer installed, you already have this data anyways and do not need to download it.
Usage
download_fsaverage3(accept_freesurfer_license = FALSE, scheme = "https")
Arguments
accept_freesurfer_license
logical, whether you accept the FreeSurfer license for fsaverage, available at https://surfer.nmr.mgh.harvard.edu/fswiki/FreeSurferSoftwareLicense. Defaults to FALSE.
scheme
character string, the URL scheme to use. Either "https" (the default) or "http". Switching to "http" can be useful as a fallback if the HTTPS server is unreachable.
Value
Named list. The list has entries: "available": vector of strings. The names of the files that are available in the local file cache. You can access them using get_optional_data_file(). "missing": vector of strings. The names of the files that this function was unable to retrieve.
Note
The subject fsaverage3 is a downsampled (low mesh resolution) version of the standard fsaverage. If you never heard about fsaverage3, you do not need it. You will have to manually re-sample your data in FreeSurfer if you want to use it with fsaverage3.
