Hi Mathieu,

sorry to bother you again, the thing is that when I try to export from the terminal it seems to fail to save the cloud because it contains 0 points

rtabmap-export --xmin -10 --xmax 10 --ymin -10 --ymax 10 --zmin -10 --zmax 10 --output section1 ~/.ros/peiramatozwo_rtabmap.db

 but when I try to export from the GUI for the same area there are 8 nodes and their points.

Any idea why is this happening ? Also I attach the database, you can also paint the points from the cameras (I am still experimenting on the calibration techniques and this is why I was asking if I can change the TF information in order to check new calibration results without redoing the mapping).
