Is there any documentation/help manual on how to use SNAP (Simulation and Neuroscience Application Platform)1.

I wanted to run the Motor Imagery sample scenario with a .avi file for the stimulus instead of the image. How can that be done?

The following error is obtained when using the AlphaCalibration scenario which gives code to play an avi file.Any help appreciated

由于文件大小，视频文件不包含在 github 存储库中。但是，如果您使用放在搜索路径上的任何其他视频文件（例如，在其他媒体文件旁边 - 另请参阅 Panda3d 的内容搜索路径概念），您的用例应该可以工作。

包含媒体文件的 SNAP 版本位于：ftp: //sccn.ucsd.edu/pub/software/LSE-SDK/，其中可能包含您要查找的文件。
