NAUTY-DIRECTG(1) Nauty Manual NAUTY-DIRECTG(1)
NAME
nauty-directg - generate small digraphs with given underlying graph
SYNOPSIS
**directg **[*-q*] [*-u|-T|-G*] [*-V*] [*-o*] [*-f#*] [*-e#|-e#:#*] [*-s#/#*] [*infile*
[*outfile*]]
DESCRIPTION
Read undirected graphs and orient their edges in all possible
ways.
Edges can be oriented in either or both directions (3
possibilities). Isomorphic directed graphs derived from the
same input are suppressed. If the input graphs are
non-isomorphic then the output graphs are also.
**-e**# | **-e**#:#
specify a value or range of the total number of arcs
**-o **orient each edge in only one direction, never both
**-f**# Use only the subgroup that fixes the first # vertices setwise
**-T **use a simple text output format (nv ne edges) instead of
digraph6
**-G **like **-T **but includes group size as third item (if less than
10^10)
The group size does not include exchange of isolated vertices.
**-V **only output graphs with nontrivial groups (including exchange of
isolated vertices).
The **-f **option is respected.
**-u **no output, just count them
**-s**#/# Make only a fraction of the orientations: The first integer is
the part number (first is 0) and the second is the number of
parts. Splitting is done per input graph independently.
**-q **suppress auxiliary information
