nengo script

Nengo uses Python to run script. To create a script open a txt document, write the script, and save it as name.py (i.e., python code). To run it, open the script from within the python environment and it will run in the same display window used by the nengo graphical interface. It is not currently possible to go back and forth between the graphical interface and script. If you want to encode a custom function into connection weights you need to use the script. The scripting language can encode any python function as connection weights. That is, nengo translates directly from python code to spiking neurons
