Pose Cell Network window dose not work

[sunt40]

After:
roslaunch ratslam_ros my_robot.launch
roslaunch usb_cam usb_cam-test.launch
rosrun topic_tools relay /usb_cam/image_raw/compressed /usb_cam/camera/image/compressed
Then four window appeared.
When I take my laptop move around the room,the Local View window works well. But the Pose Cell Network window and the Experience Map window dose not work.The activity packet didn't appear in Pose Cell Network window and the experience map also didn't appear.
How to solve this problem?

This sounds like there is no odometry now. Check that your odometry is connected properly.

I solved it! I modified the launch and opened odometry node.That's great! Thanks for your help!!

How did you fix this? If you coped my_robot.launch from one of the existing launch files, there should have already been an RatSLAMVisualOdometry node, right? Doesn't that provide odometry?
