Hi,

I am trying to use clidar_IMU_calib to align my lidar and IMU, however, after building the project and loading li_calib_gui node with command: ./src/lidar_IMU_calib/calib.sh, I got following message:

... logging to /home/neousys/.ros/log/5225dbb0-3b87-11ec-a470-0028f8cacfa1/roslaunch-nuvo-jl-19945.log Checking log directory for disk usage. This may take a while. Press Ctrl-C to interrupt Done checking log file disk usage. Usage is <1GB.
