SNAP:模拟和神经科学应用平台

Question

是否有关于如何使用 SNAP（模拟和神经科学应用平台）的文档/帮助手册1。

我想使用刺激的.avi文件而不是图像来运行电机图像示例场景。怎么能做到这一点呢？

使用AlphaCalibration 场景时会出现以下错误，该场景提供了播放 avi 文件的代码。任何帮助表示赞赏

由于文件大小的原因，视频文件不包含在 github 存储库中。但是，如果您使用放置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），您的用例应该有效。

有一个 SNAP 版本，包括媒体文件：ftp://sccn.ucsd.edu/pub/software/LSE-SDK/其中可能包括您要查找的文件。
