Nextage ros bridge simulation issue

edit

Hi everyone, I think this is not a question, but a suggestion.

I have been following rtmos tutorials, and I found an Issue with in the http://wiki.ros.org/rtmros_nextage/Tu... "Running ROS process, operating via scripts and GUI.", and specifically, in the third part: "Run python script for interactive operation".

The point is that when I run a simulation with:

ipython -i `rospack find nextage_ros_bridge`/script/nextage.py 

It always return error to connect with my simulation model.

At this point, I found the path to the main.wrl modelfile, so I satarted to use this in calls to nextage.py script by:

ipython -i `rospack find nextage_ros_bridge`/script/nextage.py -- --modelfile  /opt/ros/indigo/share/nextage_description/models/main.wrl

Checking the nextage.py script, I figured out what was happening, and is that modelfile hardcode does not exists on my system (I have installed all following tutorials).

Now I have changed the path to

 /opt/ros/indigo/share/nextage_description/models/main.wrl  

I have been reading how to suggest a change but I am not sure how to proceed, so if anyone can explain me how to proceed or suggest this change himself I would be really thankful.
