Dear chimera team / users,

I was looking for a way to save the content of Axis/plane/centroid information, not only the radii via command line, because I want to analyze the structure movement from MD trajectory. It is not convenient to save the information manually for each frame. Thanks

Hi Xiaobo, You are right that compiling that information in the context of an MD trajectory is far too difficult. Therefore, I have added code to Chimera to log all the pertinent info for axes/planes/centroids as they are created. This means you can run through the trajectory once and then save the reply log to a file to save the relevant info. I assume you are using a per-frame script to create the geometric objects. You may want to add an "echo <FRAME>" to the start of your per-frame script so it is easy to tell which frame the objects belong to. The changes were just committed, so you will have to download a daily build dated Dec. 18th or later to get them. Such a build should show up on the download page in about 12 hours (if the build succeeds). --Eric Eric Pettersen UCSF Computer Graphics Lab http://www.cgl.ucsf.edu
