NAME

     pik2dpf  - module to convert OPER pik files  to  1DIPF/2DIPF
     card set.

SYNOPSIS

     pik2dpf [ -Nnfile ] [ -Oofile ] [  -ssi  ]  [  -oorder  ]  [
     -bbias ] [ -V ] [ -? ]

DESCRIPTION

     pik2dpf converts the the digitized segments saved by program
     OPER to 1DIPF/2DIPF card sets.  The OPER picks must be saved
     in one or more groups of 3 segments each,  where  the  first
     segment  defines  the upper temporal and spatial boundary of
     the data to  be  filtered,  the  second  defines  the  lower
     bounary,  and  the  third  defines  the  fan to be REJECTED.
     Digitization of the fan requires 3  points  which  define  2
     sides  of a triangle, the apex of which points in the direc-
     tion of dip of the data to be rejected.

  Command line arguments
     -N nfile
          Enter the name of the input OPER pik file  to  be  con-
          verted.   This  parameter  is  required  and may not be
          omitted.  This input file should include  the  complete
          path name if the file resides in a different directory.
          Example -N/b/vsp/dummy tells the program  to  look  for
          file 'dummy' in directory '/b/vsp'.

     -O ofile
          Enter the name of the card file  to  contain  the  DIPF
          card  images to be used in the subsequent DIPF applica-
          tion immediately after the -O flag.   The  output  data
          set also requires the full path name (see above).

     -s sample interval
          Enter the sample interval of the data set  to  be  fil-
          tered.  This parameter is required.

     -o order flag
          Enter -ot is the trace  number  was  the  most  rapidly
          changing trace index on the digitized data (typical for
          more than one trace per  record).   Enter  -or  if  the
          record number was the most rapidly changing index (typ-
          ical for 1-trace records, as in stacked data).

     -b record bias
          Enter the difference between the  ACTUAL  first  record
          number  on the input data set and the OPER first record
          number.  Generally, OPER assigns a  "1"  to  the  first
          record.   If,  for  example.  the  actual  first record
          number is 100, the bias would be 99 (-b99).

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

     -?   Enter the command line  argument  '-?'  to  get  online
          help.   The program terminates after the help screen is
          printed.

     -H   Enter the command line argument -H to get online  help.
          The   program  terminates  after  the  help  screen  is
          printed.
