Hi! I have the part of launch file below. When I type $ roslaunch hector_slam_launch neato.launch there is this message neato.launch requires the 'trajectory_source_frame_name' arg to be set. The traceback for the exception was written to the log file. What means it? Thank!

<node pkg="hector_trajectory_server" type="hector_trajectory_server" name="hector_trajectory_server" output="screen">
<param name="target_frame_name" type="string" value="/map" />
<param name="source_frame_name" type="string" value="$(arg trajectory_source_frame_name)" />
<param name="trajectory_update_rate" type="double" value="$(arg trajectory_update_rate)"/>
<param name="trajectory_publish_rate" type="double" value="$(arg trajectory_publish_rate)"/>

When I type "$ rosrun hector_trajectory_server hector_trajectory_server", I have this message: [ INFO] [1453481701.966443199]: Waiting for tf transform data between frames /map and /base_link to become available. Is it correct?
