Hi Sandeep, To open files in an already running Chimera from your program you can use the chimera --send option. For example, chimera --send myfile.mrc You need to tell Chimera to accept "web data" for this to work. You do this using Chimera menu entry Favorites/Preferences, category Web Data, set "Accept web data" to true. Press the Save button if you want this setting to apply to all future Chimera sessions (saved in ~/.chimera/preferences). If you don't set this preference, the --send command-line option will just start another copy of Chimera. This is described in the Chimera manual where command-line options are described: http://www.cgl.ucsf.edu/chimera/1.1951/docs/UsersGuide/options.html You can do fancier things, like send Python code (*.py files) or Chimera commands (*.cmd or *.com files) to Chimera to show your data in a certain way. You would still use the --send option to send the Python file. These remote control features were added to Chimera so that a web browser link can cause commands and files to be sent to Chimera and this is described in the Chimera manual: http://www.cgl.ucsf.edu/chimera/1.1951/docs/ContributedSoftware/webdata/chim... The hard part here is that volume data display options like threshold levels do not have simple Chimera commands to set them. Instead you have to dig around in the VolumeViewer Python code (in the share directory) in order to see what Python functions set these things. This is not easy to figure out. I can help you if you have specific questions about the Python functions for volume data display. Tom

Hi Tom, sorry for being very confusing . i am trying to open up files generated from my program . as of now all i do is chimera test1.mrc

and next time i generate another file i would open it as chimera test2.mrc

so it would open a new chimera window and show the next .mrc file . what i would like to do is when i open the second file test2.mrc i would like to see it open in the already opened chimera window for test1.mrc.

do you think i can do this ? Please let me know
