2.3.11 Captures

The sensor data files you add to a Project are called Captures. A Capture can contain multiple time series columns corresponding to different devices, sensors, channels or axes, as long as all of the columns in the capture describe the same period of time.

Examples:

# to list all capture files

client.list_captures()

my_capture = client.project.captures.get_capture_by_filename("Capture Name")

my_capture = client.project.captures.get_capture_by_uuid(uuid)
