BCI2000 supports a variety of data acquisition systems, brain signals, and study/feedback paradigms. During operation, BCI2000 stores data in a common format (BCI2000 native or GDF), along with all relevant event markers and information about system configuration. BCI2000 also includes several tools for data import/conversion (e.g., a routine to load BCI2000 data files directly into Matlab) and export facilities into ASCII. BCI2000 also facilitates interactions with other software. For example, Matlab scripts can be executed in real-time from within BCI2000, or BCI2000 filters can be compiled to execute as stand-alone programs. Furthermore, a simple network-based interface allows for interactions with external programs written in any programming language. For example, a robotic arm application that is external to BCI2000 may be controlled in real time based on brain signals processed by BCI2000, or BCI2000 may use and store along with brain signals behavioral-based inputs such as eye-tracker coordinates. BCI2000 requires any of the supported data acquisition systems listed above. We provide BCI2000 with full source code and all executables, which run on most current PCs running Microsoft Windows. We provide the complete source code to the BCI2000 system. Compilation supports Borland C++ Builder 6.0 or Borland/CodeGear Development Studio 2007/2009 (all BCI2000 versions), VisualStudio, and MinGW (BCI2000 V3.0).
