x2sys_datalist

       x2sys_datalist  - A generic data-extractor ascii or binary
       files

SYNOPSIS

       x2sys_datalist file(s) [ -Ddeffile ] [ -Fname1,name2,... ]
       [  -H  ] [ -M[flag] ] [ -Rwest/east/south/north ] [ -V ] [
       -bo ]

DESCRIPTION

       x2sys_datalist reads one or more  files  and  produces  an
       ASCII  [or binary] table.  The files can be of any format,
       which must be descriped and passed with the -D option. You
       may  limit  the  output to a geographic region, and insist
       that the output from several files be separated by a  mul­
       tiple  segment header.  Only the named data fields will be
       output [Default are all columns].

       files  Can be one or more binary or ASCII data  files.  To
              give a list of names, use `cat list_of_files`.

OPTIONS

       No  space between the option flag and the associated argu­
       ments

       -D     Definition file for this data set. [x2sys.def]

       -F     Give a comma-separated  list  of  column  names  as
              defined  in  the  definition  file. [Default is all
              data columns].

       -H     Input  file(s)  has  Header  record(s).  Number  of
              header records can be changed by editing your .gmt­
              defaults file. If used, GMT  default  is  1  header
              record.

       -V     Selects  verbose  mode,  which  will  send progress
              reports to stderr [Default runs "silently"].

       -bo    Selects binary output. Append s for  single  preci­
              sion [Default is double].

EXAMPLES

       To  extract  all  data  from  the  old-style  GMT MGG file
       c2104.gmt, try:

       x2sys_datalist c2104.gmt -Dgmt > myfile

       To make x,y,topo input for blockmean and surface using all
       the files listed in the file tracks.lis, but only the data
       that are  inside  the  specified  area,  and  make  output
       binary, try:
