gcv

gcv(1)							       Scotch user's manual							    gcv(1)

NAME

       gcv - graph file converter

SYNOPSIS

       gcv [options] [igfile] [ogfile] [oxfile]

DESCRIPTION

       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, gcv 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 compres-
       sion 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.

       -iifmt Set format of input graph file, which can be:

	      bnum   Boeing-Harwell format. This is a matrix format.  Only square matrices are supported. Square matrices with unsymmetric pattern
		     are  symmetrized.	In  case  the file contains several matrices, the num parameter allow the user to provide the index of the
		     matrix to convert, starting from 0. When the num parameter is not set, it is assumed to be 0.

	      c      Chaco format. This is an adjacency graph format, also used by MeTiS.

	      m      Matrix Market format. This is a matrix format describing individual edges. Matrix pattern is symmetrized, such that rectangu-
		     lar matrices are eventually squared.

	      s      Scotch graph format. This is an adjacency graph format.

       -oofmt Set format of output graph file, which can be:

	      c      Chaco format.

	      m      Matrix Market symmetric pattern format.

	      s      Scotch format. This is the default.

       -V     Display program version and copyright.

EXAMPLE

       Convert a Matrix Market graph into a Scotch graph. Matrix Market files do not comprise geometry data, so no geometry file is needed on out-
       put:

	   $ gcv -im brol.mm brol.grf
