Hi all, I performed a SLAM navigation through a turtlebot3 in gazebo thanks to gmapping and I obtained both a .pmg and .yaml file of such a map. I have slightly artificially modified the .pmg file into GIMP to add a virtual wall. To open it in RViz through "roslaunch turtlebot3navigation turtlebot3navigation.launch map_file:=$HOME/map.yaml" I need the .yaml file of the edited version of my map. How could I do that? Thank you in advance
