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', on input only).
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
