Technical Reference:Parameter File
In BCI2000, parameters are variables describing system configuration. Parameter files (extension .prm) contain collections of parameter values. As each parameter file may contain a subset of all parameters available in a BCI2000 system, it is possible to factor out individual aspects of configuration into separate parameter files ("fragments") which may then be combined together as needed.
Parameters have a human readable representation as a Parameter Definition line. Parameter files represent collections of parameter values in the form of sequences of such definition lines, separated by Windows/DOS line separator codes.
Thus, parameter files may be modified using a standard text editor (although it will generally be easier to use the parameter editor dialog of the operator module).
