NAME
prt_pt - print data stack elements to a text file
SYNOPSIS
prt_pt <plist> <pdata> <np_start>
<np> <type> [output] [rec_num] [n_rec]
| <plist> | (input) point list (int) |
| <pmask> |
(input) point data stack of mask values (uchar,
pmask[i]=0 excludes point i, enter - if not
available) |
| <pdata> | (input) point data stack (various types supported) |
| <np_start> | starting point index to display (beginning with 0) |
| <np> | number of points to display in each layer (enter - to end of list) |
| <type> | data type (0:fcomplex 1:scomplex 2:float 3:int 4:short 5:byte 7:position 8:coordinates(int) 9:phase (fcomplex input)) |
| [output] | (output) text file (enter - for output to stdout) |
| [rec_num] | starting record number (default=1, starting with 1) |
| [n_rec] | number of records to display (default=to end of stack) |
EXAMPLE
prt_pt testsite.plist pmsk1 testsite.punw 214 5 2
testsite.unw.txt
Reads the input point list, and writes to the output ascii file the corresponding values from the input point data stack for the indicated number of points starting with the indicated starting point number.
INSTALLATION
Source code prt_pt.c in ./IPTA/src, executable version prt_pt in
./IPTA/bin
DESCRIPTION
prt_pt extracts values of the indicated number of points starting
at the indicated starting point number from a point data stack
and writes these out to a text file or standard output.
The value extraction can be restricted to a range of records of the point data stack by indicating a starting record number and a number of records to consider.
Various point data stack types are supported. Point
coordinates begin with x=0, y=0 and the point indices begin with
0.
OPTIONS
none.
