can not find keys start with 'app_'

Hi dear

After I download the comma-dataset , I can not find keys start with 'app_' in the log directory file which you wrote in your log.md.
is there something wrong with the comma-data.zip?
because I want to find which keys represent the gyro's x,y,z speed .
and which keys represent the Accelerometer‘s x,y,z value in the log's h5 file

it will be very appreciate if anyone can answer

thanks
