Add the following debug information to app:

This is to help find out whether or not the app has been mounted correctly or not.

debug = proc do |env|
  [200, { 'Content-Type' => 'text/plain' }, [ "PATH_INFO: #{env['PATH_INFO']}\nSCRIPT_NAME: #{env['SCRIPT_NAME']}" ] ]
end

map '/debug' do
  run debug
end

Also remember to have hours not exceed 24 hours % 24

At times signals are inverted in the EDF and need to be flipped to get the correct orientation. You may want to flip individual signals on a case-by-case basis. Perhaps this could be done by simply clicking on the signal name in the lefthand pane.
