ID: Segment unique ID number. xProx: x-coordinate of the proximal vertex of the segment. Either in cm or mm. yProx: y-coordinate of the proximal vertex of the segment. Either in cm or mm. zProx: z-coordinate of the proximal vertex of the segment. Either in cm or mm. xDist: x-coordinate of the distal vertex of the segment. Either in cm or mm. yDist: y-coordinate of the distal vertex of the segment. Either in cm or mm. zDist: z-coordinate of the distal vertex of the segment. Either in cm or mm. N/A: Information not used Q_fraction: Percentage of flow reserved to this segment. If 0, then the flow is determined by the CCO algorithm. branchingType: Determines the branching behaviour of the segment in the DCCO/PDCCO generation proccess. 0 for non-branching vessels, 1 for fixed vessels, 2 for standard vessels, 3 for distal vessels. radius: Radius of the segment. Either in cm or mm. vesselFunction: 0 for distribution segment, 1 for perforator segment or 2 for transport segment. ID_Parent: ID of the segment's parent. For the root segment, we set this value to -1. ID_Child01: ID of the segment's child. ID_Child02: ID of the segment's child.
