gcv - graph file converter
gcv [options] [igfile] [ogfile] [oxfile]
The gcv program converts Scotch graph files from and to other external file formats.
File igfile is converted into graph file ogfile, with optional geometry data being put in geometry file oxfile, if it is available.
When file names are not specified, data is read from standard input and written to standard output. Standard streams can also be explicitly represented by a dash '-'.
When the proper libraries have been included at compile time, dgtst 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).
Convert a Matrix Market graph into a Scotch graph. Matrix Market files do not comprise geometry data, so no geometry file is needed on output:
$ gcv -im brol.mm brol.grf
gtst(1), gmap(1), gord(1), gout(1).
