Hi, I am trying out a REST listener for selections in Chimera and need help. I can talk to Chimera over REST. I can start an Http listener in Jalview - and verify it in my browser. I have sent this command to Chimera: listen start selection rest http://134.36.162.131:64745/ Then silence. I haven't managed to provoke Chimera into sending me a SelectionChanged notification. I am making selections in the Chimera window - as I can see by the 'Inspect Selection' panel. I have also started Chimera standalone (no REST service) and tried the listen command in the command line, but yet to see any output on a selection. What have I missed or how can I diagnose what I am doing wrong here?
