The files *Hz_generator.arch.tgz contain information on action potential duration resulting from running action potential model with varying degrees of drug block for some ion channels. They are to be used with the Chaste project called ApPredict, details here: https://chaste.cs.ox.ac.uk/trac/browser/projects/ApPredict They are generated using TestMakeALookupTable.hpp from within that project. There is a helper script to convert the archives into the oldest boost version that is widely supported: make_archives_compatible_with_boost_v1_54.sh These then need to be copied into the web server location: sudo su cd /var/www/html/lookup_tables/ cp /home/pmzgm/website_lookup_tables/* . chown root:www-data *
