Cn3D is a helper application for your web browser that allows you to view 3-dimensional structures from NCBI's Entrez retrieval service. Cn3D runs on Windows, Macintosh, and Unix. Cn3D simultaneously displays structure, sequence, and alignment, and now has powerful annotation and alignment editing features.
See in 3D的缩写。允许你在线作为客户端可视并交互地观察NCBI Entrez数据库的立体蛋白序列,也可用来离线观察蛋白序列与序列排序。读取MMDB格式文件,不能读取PDB格式文件,但可以输出为PDB格式文件。这是与RASMOL的最大不同。中文使用手册,300K,PDF格式。
