What should I use as my scaling factor?

Short Answer: The scaling factor reflects the electrode spacing when you use a unit spacing of 1 between electrodes in your command file geometry.

Long Answer: When writing the geometry section in your command file, it is a good idea to use a unit spacing of 1 between electrodes. This is so the file can be used for any electrode spacing by simply changing the scaling factor in the SuperSting™ Data File Setup Menu (see image below). By having 1 unit spacing, the scaling factor simply reflects the new electrode spacing. Only one command file needs to be loaded for each electrode array type used, even if different electrode spacings will be used later on.
