I have a bag file containing the path my robot traversed using a laser sensor. This is the information of the bag file:> labcoro@Samsung:~/catkin_ws_youbot$ rosbag info planner_path1.bag

I need to display the save data again in rviz but I do not know what the Fixed Frame of the bag is?
I run these command sequentially:
rosparam set use_sim_time true
rosbag play --clock planner_path1.bag
rosrun rviz rviz
another problem is that the bag dose not play and it gives this message:
[ INFO] [1484952163.366887588]: Opening planner_path1.bag
Waiting 0.2 seconds after advertising topics... done.
Hit space to toggle paused, or 's' to step.
Any suggestion?
Thanks.
