Dear VesselExpress team,

I ran into issues of being slow when using vesselExpress CLI to analysis heart light sheet images. Seems to me that the graph analysis is running on single thread and it took too long to finish. For example, I gave my task 64 cores but it took more than 120 hours to process the segmented vessels from a sub-volume for the size of 500x8000x8000 (ZYX, voxel size 0.5 um). Is there anyway to make the graph analysis step runs faster?
