Reference to run commands on Linux:

$ python tools/analytics/imu_analytics.py -i dataset -c tools/config/mynteye/mynteye_config.yaml -al=-1.2,1.2 -gl= -gdu=d -gsu=d -kl=

Reference to results on Linux:

$ python tools/analytics/imu_analytics.py -i dataset -c tools/config/mynteye/mynteye_config.yaml -al=-1.2,1.2 -gl= -gdu=d -gsu=d -kl=
