Each algorithm will create a new subdirectory, using its own name, below this path, whenever the algorithm is run for the first time with the database recording set on. For example, after the first execution of ISO_4_EMR with the default database recording conditions set on, the user will find the following subdirectory: /var/opt/WLR/database/data/measured/Iso_4_emr: /var/opt/WLR/database/data/csv_files: All CSV files are located here, either as actual files, or as links to user-specified file names. /var/opt/WLR/database/data/graphs: All executable graphics files are located here, either as actual files, or as links to user-specified file names. /var/opt/WLR/database/data/eps_save: When you print to an EPS, PNG or PDF file, the default path is this directory.
