Question

是否有关于如何使用SNAP（模拟和神经科学应用平台）1的文档/帮助手册。

我想运行带有.avi文件的Motor Imagery示例场景，而不是图像。怎么办？

使用AlphaCalibration方案时会出现以下错误，该方案提供了播放avi文件的代码。非常感谢

Answer 1

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 - 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：ftp://sccn.ucsd.edu/pub/software/LSE-SDK/中的媒体文件，其中可能包含您要查找的文件。
