gbase(1) Scotch user's manual gbase(1)NAMEgbase - sets the base value of a source graph
SYNOPSISgbase [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 eas‐
ily 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 com‐
pressed file extension, such as in 'brol.grf.bz2' or '-.gz'. The com‐
pression 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
