Hi Randy,
I am evaluating Chimera as a tool for providing (pseudo-interactive) vis functionality from a web server and therefore would like to use it in a non-gui mode.
I'm not completely clear on what you mean by this. Exactly what type of functionality do you want to provide? Do you plan on using Chimera on the server-side, or client-side? There are several different [potential] solutions here, depending on what it is you want to do: (1) Chimera as a web-browser client A locally installed copy of Chimera can be used as a web browser 'helper application', responding to certain links clicked on in a web browser. These links contatin information about files to open, and commands or python code to execute in Chimera (Chimera runs in its own window -- not embedded in the browser). See http://www.cgl.ucsf.edu/chimera/docs/ContributedSoftware/webdata/webdata.htm... for more information. (2) The IDLE interpreter Currently, the only way to access Chimera's Python API in an interactive fashion is through the IDLE window (Tools->Programming->IDLE) from within Chimera. This, of course, requires having Chimera running in normal (i.e. not 'nogui') mode. If there is sufficient demand, we may include an 'interactive nogui' mode, that gives you access from the shell. (3) chimera --nogui As you already know, Chimera can be started with the '--nogui' flag, which doesn't bring up any graphics windows, and is used mainly for carrying out molecular calculations. Since there is no graphics window, it is not possible to do any visualization (including saving images). This sounds like an interesting problem - please let us know if any of these solutions are appropriate, or require further explanation. --Dan Greenblatt ---------------------------- Daniel Greenblatt UCSF Computer Graphics Lab dan@cgl.ucsf.edu
