Arguments for sh_plotvel: 
 
  
 Script to plot station velocities on a map, using a GLOBK prt file as input.
 
 Options allow selection of stations, multiple velocities, and enhanced maps. 
 
 Basic usage : 
  
            sh_plotvel -f <file> -s <site>      
 
    -file              : Input GLOBK prt file or GETREL file
    -site              : 4-char station id of reference site for velocities
                         If site omitted, plot absolute velocities
  
 With no additional options specified, the map features will be taken from the 
 global map in the GMT library.  Three mutually exclusive options are available 
 to obtain enhanced or specialized maps: 
 
   -mapscript file     : Execute the shell script [file] to produce the map 
                           See sh_map_turk in gs/com for a template 
 
   -map list           : Use the list of maps specified from ~/gg/maps/[file]
 
   -maplist file       : Overlay the maps with full pathnames specified in [file] 
 
      With either of these last two options, you should set the range of the map using the option 
   
   -maprange type      : Calls sh_map_elements with the keyword <type> to select a region.
                         Among those allowed are <world> <europe> <turkey> <cal> 
                         See sh_map_elements for a complete list or to add your own
 
      and if a coastline map is not included, you must specifiy -coast to get the GMT coastlines.
 
 Output:
 
   -c[omment]  text    : Title for plot.  No need for quotes. This option should be issued LAST 
 
   -figcap             : Turn off figure caption mode. Header is off; comment is figure caption.
 
   -h[eader]           : Turn off header prints. Default is ON, print header.
  
   -p[rinter]  name    : Printer name.  If null use system default. 
  
   -ps file            : postscript save file. Default is FILE.SITE.ps
