Total length | Pixels or mm | The total length of all root material; can be calculated separately for each plant and each root within a plant |

Average length | Pixels or mm | The average length of all roots in a given plant; can calculate separate values for all roots or just primary or lateral roots |

Primary root count | | The number of primary roots in a given plant |

Lateral root count | | The number of lateral roots in a given plant; can also calculate the number of lateral roots for a given primary root |

Convex hull area | Pixels^{2} or mm^{2} | The area of the convex hull that encompasses all rot material belonging to a given plant |

Tortuosity | | The true length of a given root divided by the Euclidean distance from the source to the tip of that root; an average of this value for all roots in a given plant can also be calculated |

Maximum width | Pixels or mm | The maximum width of the root system for all depths; only points at equal depths are considered |

Maximum depth | Pixels or mm | The maximum depth achieved by the root system |

Network aspect ratio | | The maximum width of the root system divided by the maximum depth; providing a measure of the aspect ratio of the root system |

Width profile | Pixels or mm over length | A two-dimensional data set showing the measurement of the width of a plant root architecture over changes in depth |

Curvature profile | Degrees over length | A two-dimensional data set showing the angle of curvature of the root over changes in depth |
