nauty-nbrhoodg - extract neighbourhoods of vertices
nbrhoodg [-lq] [-c|-C] [-d#|d#:#]
[-v#|-v#:#] [infile [outfile]]
- Extract neighbours of vertices of a graph.
- The output file has a header if and only if the input file does. No
isomorph reduction is done.
- -l
- Canonically label outputs (default is same labelling as input)
- -C
- Extract closed neighbourhoods instead.
- -c
- Extract non-neighbourhoods instead.
-d# -d#:# Only include vertices with original
degree in the given range
-v# -v#:# Only include vertices with these vertex
numbers (first is 0).
- No empty graphs are output. For digraphs, out-degree and
out-neighbourhoods are used.
- -q
- Suppress auxiliary information
