I experimented with adding steering control to AMBER and Chimera (a
molecular visualizer at UCSF) using the Reality Grid steering toolkit.
It was an interesting experiment, and I got as far as being able to
retrieve parameters from a running AMBER simulation and change them (for
exmaple, the TEMP0 variable can be changed, to achieve a dynamic
temperature schedule). In principle, more complex data types like atom
coordinate vectors, etc,
can be modified, but I didn't get that far. The steering toolkit was
architected in a way that made it very difficult to get reliable
behavior. i don't consider my example usable off-the-shelf, but I am
still looking for a good steering toolkit, as I would like to
incorporate this feature into our visual workflow environment.
