NAME

     psi2ppg - converts converts pressure or pressure above  nor-
     mal
      data (PSI units), to pressure gradient (PPG units).

SYNOPSIS

     psi2ppg [-N ntap] [-O otap] [-dz dz] [-mode mode] [-nhg nhg]
     [-met] [-eng] [-V] [-?]  [-h]

DESCRIPTION

     psi2ppg will create an output pressure gradient dataset.  in
     the line header.

  Command line arguments
     -Nntap
          Enter the name of the input pressure dataset.

     -Ootap
          Enter the name of the output pressure gradient.

     -nhg nhg
          Enter the  normal  hydrostatic  gradient  after  typing
          -nhg.  The default is .465 which is correct for the USA
          Gulf Coast area.

     -mode mode
          Enter the pressure conversion mode.

     -met If this flag is present on the command  line,  it  will
          indicate  that  the  depth  sample  rate from the input
          overburden gradient dataset is in meters/second.

     -eng If this flag is present on the command  line,  it  will
          indicate  that  the  depth  sample  rate from the input
          overburden gradient dataset is in feet/second.

          Note:  Units must be specified on the command line.

     -V   Enter the command line argument '-V' to get  additional
          printout.

     -?   Enter this (or '-?' if you are running in  c-shell)  to
          get  online  help.   The  program  will terminate after
          printing this.

     -h   Enter this option to get online help.  The program will
          terminate after printing this.
