BCI2000CHAIN

The BCI2000 command-line tools allow the online processing performed by BCI2000 to be recreated exactly offline. This is possible because online BCI2000 modules consist of a chain of filters, each filter being implemented in a self-contained source file. We can therefore take the individual filter implementations and build them singly, as separate executables that can be called from the system command-line. Recreating a preprocessing chain offline is then a question of passing a stream of data through a chain of these filter tools, connected by an operating-system "pipe". The bci2000chain function uses the command-line tools, but hides the details and presents itself to you as a single Matlab function.
