GSTAT(L)		  CSDS Commands			 GSTAT(L)

NAME
     gstat - calculate 3-D chemical geometry statistics

SYNOPSIS
     gstat [ -j	]  jobname [ -version ]	[ -help	] [ <  input_file
     ] [ > output_file ]

DESCRIPTION
     gstat  calculates	geometry  statistics  using   information
     derived  from  quest(l).	It  reads  commands from standard
     input, writes to standard output and also writes a	number of
     listing files.

OPTIONS
     -j	jobname
	  Specifies the	root filenames	for this  run  of  gstat.
	  This option must be specified.

     -version
	  Gives	details	of the current version of the CSDS.

     -help
	  Print	these man pages.

ENVIRONMENT
     gstat recognises the same environment variables as	quest(l).
     When  the	CSDS  was  configured  (using  config.sh) default
     values were (implicitly) assigned to the  environment  vari-
     ables:   CSDHOME and CSDMACHINE. They can,	however, be over-
     ridden  by	 explicitly  defining  them  wthin  the	  current
     environment.

     CSDHOME
	  Look for auxiliary executables, scripts and  tables  in
	  the  sub-directories pointed to by $CSDHOME This direc-
	  tory should be accessible to all potential users of the
	  Cambridge  Crystallographic  Data  System  and  must be
	  accessible by	gstat.

     CSDMACHINE
	  Use	the    binary	 executables	from	directory
	  $CSDHOME/bin/d_$CSDMACHINE.  It is possible, especially
	  with the network file	system (NFS), to  have	different
	  types	of machines accessing the database. This variable
	  specifies the	current	machine	type to	the CSDS.

     CSD_CDROM_FILENAMES
	  If defined, CSD_CDROM_FILENAMES should be a script that
	  reads	filenames/directory_names from standard	input and
	  writes the equivalent	CD-ROM names to	standard  output.
	  For  example	if  the	 filenames in the cdrom	appear as
	  uppercase with version  numbers  then	 (in  the  Bourne

	  shell) type:

	  CSD_CDROM_FILENAMES="eval tr '[a-z]' '[A-Z]' |  sed  -e
	  '/[^/]$/s/$/;1/'"
	  export CSD_CDROM_FILENAMES

	  This	will  translate	  such	 names	 as   csds/   and
	  csds/version.txt   to	  CSDS/	  and  CSDS/VERSION.TXT;1
	  respectively.

FILES
     Input Files:

     jobname.dat
	  Structure information	is to be read from this	 file  in
	  FDAT format.

     jobname{.frg,.fgn}
	  Fragment values used in quest	run.

DIAGNOSTICS
     The diagnostics produced by gstat are explained in	Volume	4
     of	the "CSD System	Documentation."

BUGS
     The functionality of gstat	has been dived	between	 the  two
     programs vista(l) and quest(l).
