Hi I am having problem with creating map(.pgm and .yaml) files.
First i tried to create a map using the existing bag file following [this](http://wiki.ros.org/slam_gmapping/Tutorials/MappingFromLoggedData#download) tutorial. I was successful to create map.
Now I created a bag file following [this](http://wiki.ros.org/rosbag/Tutorials/Recording%20and%20playing%20back%20data) tutorial. I created a bag file. But when I try to create a map using this newly created bag file I am getting the message
ras@ubuntu:~/bagfiles$ rosrun map_server map_saver -f ~/testmap
[ INFO] [1470969136.155361289]: Waiting for the map
I am confused what is wrong with creating the bag file.
This is to mention, when i created bag file I made
rosparam set use_sim_time false
and when I create map using bag file I made
rosparam set use_sim_time true
Can anyone please help me regarding this.
Thanks.
