NAME
gbase - sets the base value of a source graph
SYNOPSIS
gbase [options] bval [igfile] [ogfile]
DESCRIPTION
The gbase program allows one to set to bval the base value of a
source graph, that is, the starting index used to number its
vertices and edges. The base value can be set to 0 or 1, so that
graphs can be easily imported from and/or exported to tools written
in C or Fortran. Scotch can handle graphs irrespective of their base
value.
When the proper libraries have been included at compile time, gbase
can directly handle compressed graphs, both as input and output. A
stream is treated as compressed whenever its name is postfixed with
a compressed file extension, such as in 'brol.grf.bz2' or '-.gz'. The
compression formats which can be supported are the bzip2 format
('.bz2'), the gzip format ('.gz'), and the lzma format ('.lzma').
OPTIONS
-h Display some help.
-V Display program version and copyright.
EXAMPLE
Set the base of graph 'brol.grf' to 1, and write the modified graph
to file 'brol_b1.grf'.
$ gbase 1 brol.grf brol_b1.grf
