gait

The gait command allows you to run gait event detectors (see available gait modules for details).

In the GUI, selecting the gait command in the left-hand panel produces this screen:

event-gait-gui

Here:

  • file_data: Launches a file browser where you should select a standardized NeuroFlow .CSV file to run gait event detection on.
  • detector: Select the detector from the dropdown.
  • detector_params: Enter any custom parameters (see the parameters listed under each detector for reference) as a dictionary-like string ({"parameter_one": value_one, "parameter_two": value_two, ...})
    • For example:

detector-params

  • savefile: Browse/enter the filepath for the exported .CSV file. If left blank, the exported .CSV file will be automatically named and placed in the same folder as the source file.

Example

Download the sample standardized Axivity .CSV data here: data-gait.zip

In the GUI window:

  1. Under file_data select the extracted sub-01_ses-01_neuroflow-axivity.csv file.
  2. Select nimbalwear-ankles from the detector dropdown.
  3. Set savefile or leave blank for default export path.
  4. Click Run in the right-hand panel to export a .CSV file with gait data appended to the source data.

Tip

Try re-running the above steps but with a different detector or with custom detector_params (e.g. {"pushoff_threshold": 0.95}). Use the validate command to inspect differences in the event detection.
