PKX_HEADERS

Format: pkx_headers [-switch value] input_file

Inputs

The input file may either be a packetized science file with the .pkx, .ulx, .bdx, .shx extensions, or a raw POD file. This tool can handle both swapped and unswapped data from any platform.

The first 26 bytes of the packet header are displayed in reverse order. Specific columns are labelled:

    words: words per line
    pkts:  packets per frame
    dcf:   dcf number
    time:  time code (low word to high)
    line:  line number
    fram:  frame number
    fm:    packet format code
    ln:    packet length code
    in:    instrument code

none

-start (-s)

The starting packet number (first is 1)

-number (-n)

The number of packets to list (default=12)

The name of the (new) text file to write the results into. This defaults to stdout if missing.

$ pkt_headers N4D904G6Q.PKX

This command will list the first twelve packet headers to the screen.

% pkt_headers test.pod -s 2 -n 20

This command will dump packets 2-21 to the screen. This usually skips the .shx packet which is ordinarily the first packet in a POD file.

% pkt_headers o45942asq.pkx -n 99999 -o o45942asq.pkt

This command will list all the packet headers to the text file named o45942asq.pkt
