S1 Videos zip target -

Once you have downloaded all of the ZIP Segments and this ZIP Target file to the same folder and renamed all files to have the same root name, open this target file (with “.zip” extension) to navigate the folders and view the videos. Alternatively, after downloading all ZIP and ZXX files into a folder, unzip all files by opening the .ZIP file with a compressing software such as WinRAR, WinZip, or 7-Zip. This will give access to the 177 GorillaFACS video examples organized in their respective folders for each AU and AD. Video captions for each video can be found in the S2 File. https://doi.org/10.1371/journal.pone.0308790.s031 (ZIP)
