scotch_gbase-int641
Sets the base value of a source graph
Part of scotch_gbase(1).
Usage
gbase [options]
bval
[igfile]
[ogfile]
Overview
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').
