I'm trying to construct the variation graph as stated in "Working with a whole genome variation graph" in the github wiki of variation graph toolkit and then convert it to gfa for experimental purposes. I manage to create the .vg graph but when i try to convert it to .gfa format with
vg view command, an empty gfa file is created and the process just hangs in the terminal with no result.
The exact command i use is:
vg view human.vg >human.gfa
The command used for creating .vg is:
vg construct -r ref.fa -v vcf_file.vcf.gz >human.vg
Any suggestions on what the problem might be?
