This is a easy-to-use platform to run BCI experiments. This platform provides basic functions such as experimental configuration, data streaming, and offline analysis. Different experiment paradigms and external device drivers can be implemented through plug-in development.

0. Install Visual Studio 2018 or later, clone MarukoLib and SharpBCI into same folder.
1. Open Visual Studio as administrator and create a new empty Visual Studio solution.
2. Add all projects in repo MarukoLib except 'MarukoLib.Dragonfly' and 'MarukoLib.Tests' to the created solution.
3. Add 'SharpBCI.Core', 'SharpBCI.Extensions', 'SharpBCI' projects into the solution.
4. (Optional) Add some plugin projects into the solution as your wish.
5. Set SharpBCI as the startup project.
6. Build and run the solution.

After the completion of a session, you can see some files that have the same filename but different suffixes in the data folder:

• .mkr Experiment marker with timestamp with timestamp. (ASCII; Comma-separated)
• .dat Biosignal data with timestamp. (ASCII; Comma-separated)
• .gaz Eye gaze point data with timestamp. (ASCII; Comma-separated)
• .vfs Video frames with timestamp. (Binary)
• .scfg Session configuration, can be used to restart the experiment. (ASCII; Json)
• .session Session information. (ASCII; Json)
• .result Result of the experiment. (ASCII; Json)

• .\SharpBCI.exe "xxx.scfg" Directly run the predefined session.
• .\SharpBCI.exe "xxx.mscfg" Run multiple predefined sessions in one go.

You can implement a paradigm easily by defining your own Paradigm with desired paramters and corresponding ParadigmFactory.
