an error in seed coordinates

[neperchh]

dear professor
I want to generate a model using my seed coordinates from EBSD dates. However, when I input 4 coordinate points randomly, the output is only one rectangle.When I used my EBSD dates,I cannot obtain .tess file.The following is my code and random seed coordinate and results. Can you help me? Thank you very much.
code : neper -T -n 4 -morphooptiini "coo:file(coo1),weight:0" -morpho voronoi -dim 2
seed coordinate：
1 10
2 5
3 7
4 6

You are working in the default, unit square domain. Use -domain to specify the actual shape/size.
