ROSBAG HECTOR-SLAM

Hi guys, I'm trying to record a hector-slam map with rosbag and then trying to reproduce it. The thing is I really don't know what should I record and how to reproduce it back in the RVIZ like this: rosbag play Team_Hector_MappingBox_RoboCup_2011_Rescue_Arena.bag --clock This is my launch file right now. where in args I've tried /rviz, /scan, /map Also tried with the command: rosbag record /path/to/file /topic and then rosbag play file.bag What should I modify to get what I want? (reproduce the created map)
