Data collected from 10 subjects with Actigraph GT9X Link IMUs attached to waist and head.
Data is stored in the netCDF format with the following specification:
Dimensions:
axis: ('x', 'y', 'z')
sample: datetime64[ns]
Coordinates:
gender string (M/F)
age int64
weight int64
height int64
subject_id string (001-010)
Data variables:
AccHead (sample, axis) float64
GyrHead (sample, axis) float64
AccWaist (sample, axis) float64
GyrWaist (sample, axis) float64
Accelerometer measurements of head (AccHead
) and waist (AccWaist
) are stored in g (1g = 9.81m/s). Gyroscope measurements of head (GyrHead
) and waist (GyrWaist
) are stored in rad/s. Excluded periods for either sensor location are stored as nan
.
Files are stored in data/XXX.nc
where XXX
is the subject identifier (001
-010
). Demographic information is additionally available in data/subject_info.csv
