I am trying to add VCF to a graph (DAG) using ./vg add module. But once the process is completed, I found that there are cycles in the graph.

I used the following command: ./vg add -v file.vcf.gz graph.vg > new_graph.vg

"add" is a deprecated module in vg. Do the vg toolkit has any other module which does this job? If not, then how can I resolve this issue with add module ?

Thank You
