Dear All I'd like to use the commond "savepos" or "scene" to save the maps' rotations and translations relative to input coordinates, etc., but when I used the command: ~savepos ****(a name I write) , or ~scene ***** There are errors reminder:No position named *****, or No scene named **** The versions I have tried include 1.6.1-linux_x86_64 and 1.6.2-linux_x86_64. Both of them have same problems. Could you kindly tell me how to use the savepos or scene, or how to resolve my problems? Millions thanks Qinfen ************************************************ （Qinfen Zhang）（Ph.D） Bio.EM.Lab,School of Life Science, Zhongshan（Sun Yat－sen） University Guangzhou, 510275,P.R.China Tel:86-020-84112286(Lab) http://scholar.google.com/citations?user=Wj62cPoAAAAJ&hl=en http://sklbc.sysu.edu.cn/Team/User/info.aspx?typeid=283&pid=80 http://bioem.sysu.edu.cn ************************************************
