Optional data for R-package from publication: "fsbrain: an R package for the visualization of structural neuroimaging data"

This is the optional data that be downloaded from within the R packages 'freesurferformats' and 'fsbrain'. See publication: https://doi.org/10.1101/2020.09.18.302935 Due to CRAN limits, this data cannot be stored in the package. The author therefore stores this on a private server, which is not optimal. This uploads serves as a backup and an alternate way to access the data, e.g., for future maintainers of the software. Note that the files in directories 'subjects_dir/fsaverage' and 'subjects_dir/fsaverage3' are part of FreeSurfer6 and distributed under the FreeSurfer license.
