User Reference:BCI2000Watchdog

Introduction

BCI2000Watchdog is a program that monitors the function of a running BCI2000 instance, and restarts it if malfunction is detected. Functioning of BCI2000 is determined by monitoring "Canary expressions" which are evaluated in the context of BCI2000 and are expected to change on a regular basis, e.g. the time stamp of the currently processed data block, and/or the frame number of a video recorded alongside brain signal signal data.

Using BCI2000Watchdog

Selecting a BCI2000 Startup Batch File

The top element of BCI2000Watchdog holds the full path to a BCI2000 startup batch file. This may be any BCI2000 batch file, except that it must contain the SET CONFIG and START commands. If the batch file does not contain these commands, SetConfig and Start must be presses manually, so the watchdog will be unable to start operation of BCI2000 when it tries to restart it.

Pressing the "..." button at the right side of the edit field will bring up a file selection dialog, so you don't need to enter the full path manually.

Also, dragging a batch file onto the edit field will enter the file's full path.

In addition, a batch file may be given on the command line when starting up BCI2000Watchdog, or by dragging-and-dropping onto the program's icon.
