有没有关于如何使用 SNAP(模拟和神经科学应用平台)的文档/帮助手册1.
我想使用 .avi 文件作为刺激而不是图像来运行运动意象示例场景。这怎么办?
使用 AlphaCalibration 场景时出现以下错误,该场景提供了播放 avi 文件的代码。任何帮助表示赞赏

由于文件大小,视频文件未包含在 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。
有一个包含媒体文件的 SNAP 版本,位于:ftp://sccn.ucsd.edu/pub/software/LSE-SDK/,其中可能包含您正在查找的文件。
