Cannot use own bag file

[jer1234]

I am using VLP16 , and the .pcap I converted using velodyne_driver ,and then record as it .bag But when I try to use it with the your system nothing appear in Rviz , Seem like it did not detect my bag file. The mapping run smoothly with your .bag file but not mine

Could you check if the prefiltering nodelet is connected with the points topic using rqt_graph?

look like it is not connected, what should i do?

Check the points topic name in your bag and remap "/velodyne_points" of prefiltering_nodelet following "Use hdl_graph_slam in your system" in README.
