NAME
nauty-nbrhoodg - extract neighbourhoods of vertices
SYNOPSIS
nbrhoodg [-lq] [-c|-C] [-d#|d#:#] [-v#|-v#:#] [infile [outfile]]
DESCRIPTION
-
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
