Hello,
I'm very new to nauty.
I want to remove isomorphs from a (smallish for now) list of 525 (small) digraphs.
Since shortg only mentions undirected graphs I used
./amtog -s list-of-digraphs | ./labelg | sort | uniq
However I get a lot of warnings that the matrices are unsymmetric (obviously).
To test this it seems something goes wrong since
running one of graphs of the output through ./showg
gives a undirected (or multi-)graph!?
Is there a good/better way to do this?
Thanks for any assistance,
Christian
