Hi, all I'm trying to record certain topic(/scan) from the /hokuyo_node. I runned "rosbag record /scan" command while /scan topic is publishing. But rosbag recorder always attached to /clock topic and couldn't create beautiful bag file. Is anyone who knows how to solve this? Thanks. http://ros-users.122217.n3.nabble.com/file/n1772711/Screenshot-2.png -- View this message in context: http://ros-users.122217.n3.nabble.com/rosbag-record-a-always-creates-4117B-file-tp1772711p1772711.html Sent from the ROS-Users mailing list archive at Nabble.com.
