Hi Fei, Oh, the bracket symbols [ ] should not be included in your command. They just mean that the keyword and value are optional and could be omitted if the default is what you want. For example, an image-saving command could be: save /Users/meng/Desktop/proteasome.tiff transparent true The size would be the same as your graphics window, and the format is known from the output filename. The defaults are described in the manual: <http://rbvi.ucsf.edu/chimerax/docs/user/commands/save.html#image> This page explains the meanings of brackets and fonts in the command usage descriptions: <http://rbvi.ucsf.edu/chimerax/docs/user/commands/usageconventions.html> I hope this helps, Elaine ----- Elaine C.

Hi Elaine, Thanks for your kindly reply, and I can move the object I want to move with your suggestion. BTW, when I want to save the image of the result by using save command line, "save [ image ] proteasome [ format tiff ] [models #1] [[ width 2457 ][ height 3000 ]| pixelSize 0.4] [ supersample 3 ] [ quality 95 ] [ transparentBackground true ] ", there is a warning of "Expected a models specifier or a keyword". Any advice? Thanks a lot. Best, Fei
