This dir deals with graphical or file output. L5P_history.g can be used to save spike times (of neurons or fibres) to a file. L5P_ascout.g is commonly used to write time series (of membrane potential, electrode LFP, etc) to a file. L5P_view.g will open a window picturing all the neurons' compartments, colour-coded by membrane potential and updated every 50 ms. Likewise, L5P_graphsolve.g will open a window with online graphs of the time-evolution of the membrane potential of selected compartments. Note that L5P_graphsolve.g replaces L5P_graph.g because of an unsolved problem with Genesis or my code. The original code of L5P_graph.g intended to establish the messages from compartments to graphs before setting up the hinessolver. Unfortunately this resulted in a bus error. So L5P_graphsolve.g now makes these messages directly from the hinesolver element to the graphs, after creation of the hinessolver element.
