模拟与神经科学应用平台

Question

是否有关于如何使用模拟和神经科学应用平台(1)的文档/帮助手册？

我想用一个用于刺激的.avi文件来运行运动图像示例场景，而不是图像。怎样才能做到呢？

使用AlphaCalibration场景时会获得以下错误，该场景提供代码来播放avi file.Any帮助。

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

有一个包含在：ftp://sccn.ucsd.edu/pub/software/LSE-SDK/的媒体文件的SNAP版本，它可能包含您要查找的文件。
