Hi Sakina,

Here is an example:

$ rosrun rtabmap_ros rtabmap \
   odom:=/my_odom_topic \
   rgb/image:=/camera/rgb/image_rect_color \
   rgb/camera_info:=/camera/rgb/camera_info \
   depth/image:=/camera/depth_registered/image_raw \
   _frame_id:=camera_link \
   --delete_db_on_start

Parameters should have an underscore prefix ("_") while topics not. Verify that remapping is okay with corresponding message on the terminal:
