Extract neighbourhoods of vertices

Usage

nbrhoodg [-lq] [{-c | -C}] [{-d# | d#:#}] [{-v# | -v#:#}] [infile [outfile]]

Overview

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
