1) install TSOM: run "tsom_setup.exe";
2) copy the TSOM folder provided here onto the TSOM folder create during the previous installation step (e.g. "D:\TSOM");
3) run MATLAB and move the current folder to "AnalysisTSOM" within the TSOM installation folder tree (e.g. "D:\TSOM\MATLAB_ROOT\AnalysisTSOM");
4) exec the MATLAB script "app_frontiers2019_1_tsom_training.m" to train (or train again) the TSOM model on the ARABIC, ENGLISH, GERMAN, GREEK, ITALIAN, and SPANISH datasets
   (by using 6 cores at 3GHz each, this may take two or three hours per language and per frequency distribution);
5) exec the MATLAB script "app_frontiers2019_2_export_data.m" to process the TSOM trained data and to export data for subsequent R analysis;
