# nauty-dretodot - Man Page

read graphs and initial coloring in dreadnaut format and write in dot format

## Synopsis

**dretodot** [*-S#:#ixF#o#m#n#r#:#*[*r#*]*d#g*] [*infile.dre* [*outfile.dot* [*outfile.dre*]]]

## Description

Read graphs and initial coloring in dreadnaut format. Write graphs in dot format to outfile.dot. If outfile.dre is given, write the input graph and the partition, as modified by the **-F** and **-i** options, to outfile.dre. outfile.dre is allowed to be the same file as infile.dre.

- -V
Set max number of vertices (default 1000).

- -E
Set max number of edges (default 5000).

- -v
Set verbose mode (default NO).

**-S**#:# Set maximum width and height of the drawing, in inches

(default 10 x 6.18).

- -i
Refine the partition before drawing (default NO).

- -x
Draw the orbit partition, computed by Traces. (default NO).

- -F#
Individualize vertex # (and refine the partition).

- -o#
Label vertices starting at # (default 0). This can be overridden in the input.

- -m#
Set the drawing model (see http://www.graphviz.org): 0 (or any value different from 1,...,5)=dot (default 0), 1=neato, 2=fdp, 3=sfdp, 4=twopi, 5=circo.

- -n#
Scale the size of vertices in the drawing (#=0,1,2; default 1).

**-r**#:# (**-r**#) Set the vertices to be drawn at the topmost level

in a hierarchical (dot model) drawing (default none). Any sequence of **-r**#:# (r#) options is allowed.

- -d#
Draw the graph induced by vertices at topmost level and by vertices at distance # from them; example: ./dretodot

**-n2 -r1 -r12**:17**-d2**MyGraph.dre Outfile.dot.- -g
Highlight the induced subgraph into the whole graph.

Only dreadnaut commands $,$$,g,n,f,",! are recognised; no digraphs.
