Hi,

Maybe just a little off-topic, but related to steered molecular
dynamics in a way. Some people at the Technical University of
Delft (The Netherlands), mainly Michal Koutek, have been integrating
Molecular dynamics with virtual reality. A ligand could be steered
on-the-fly out of a pocket using GROMACS, just by exerting a force on
the atoms. If I remember correctly, it resembles studies performed
in the group of Klaus Schulten (I remember having seen some people
dragging molecules through a ion-channel with a VR-glove). Koutek
and coworkers have been able to bring this into the from of a
simple Workbench. I have included some reference to this work and
a spin-off company (FolDyne). I see no reason why this couldn't be
done with AMBER...

regards,

aldo
