NAME

6       gbase - sets the base value of a source graph
7

SYNOPSIS

9       gbase [options] bval [igfile] [ogfile]
10
11

DESCRIPTION

13       The  gbase program allows one to set to bval the base value of a source
14       graph, that is, the starting index used  to  number  its  vertices  and
15       edges.  The base value can be set to 0 or 1, so that graphs can be eas‐
16       ily imported from and/or exported to tools written  in  C  or  Fortran.
17       Scotch can handle graphs irrespective of their base value.
18
19       When the proper libraries have been included at compile time, gbase can
20       directly handle compressed graphs, both as input and output.  A  stream
21       is  treated  as  compressed  whenever its name is postfixed with a com‐
22       pressed file extension, such as in 'brol.grf.bz2' or '-.gz'.  The  com‐
23       pression  formats which can be supported are the bzip2 format ('.bz2'),
24       the gzip format ('.gz'), and the lzma format ('.lzma').

EXAMPLE

32       Set the base of graph 'brol.grf' to 1, and write the modified graph  to
33       file 'brol_b1.grf'.

35           $ gbase 1 brol.grf brol_b1.grf
