I do not think Chimera could run using Jython because Chimera uses
dozens of compiled C/Python modules.
You can communicate with Chimera via a pipe. One approach is to start
Chimera with a popen() system call and send commands to Chimera's stdin
using the ReadStdin capability:
It is also possible to talk to an already running instance of Chimera
using the "chimera --send <file>" shell command. This is used to have a
web browser helper application directly send files to Chimera.
The implementation uses a socket that Chimera is listening on but it is
somewhat tricky to find the right port number. It is saved on the local
machine in a file as a security measure to prevent network connections.
The details of that implementation are in your Chimera distribution
Scooter Morris in our lab has written code to communicate with Chimera
from a Java application called Cytoscape. He might be able to provide
