HEADER(1)							     HEADER(1)

NAME
  header - to read and display the header of an MRC image file.

SYNOPSIS
  header [options] filename(s)

DESCRIPTION
  A simple program to read and display the information in the 
  header of an MRC image file - image size, data type, min, max, etc.
  The program will accept the file name either from the command line or
  as an entry to the program after it is started.  If there is no file
  name or other arguments on the command line, the program asks for an 
  input file name.

  If no options are given, the program will print the complete standard header
  output.  If any of the output options describe below are given, then the
  program prints only the numeric output for the given options, without any
  descriptive labels.  If multiple options are given, each option will produce
  one line of numeric output, with the output in the order that the options
  appear below (and that the output appears in the standard header output).
  If multiple file names are entered, then all of the header entries will be
  printed for one file, then for the next, etc.

  The options are processed by the PIP package (see man page for pip).
  They are:

 -input OR -InputFile   File name
    Input image file.  All nonoption arguments will be treated as input files.
    (Successive entries accumulate)

 -size OR -Size
    Output image dimensions

 -mode OR -Mode
    Output data mode

 -pixel OR -PixelSize
    Output pixel spacing in angstroms

 -origin OR -Origin
    Output origin values

 -minimum OR -Minimum
    Output minimum value of data

 -maximum OR -Maximum
    Output maximum value of data

 -mean OR -Mean
    Output mean value of data

 -brief OR -Brief
    Output brief header with dimensions, pixel size, mode, minimum, maximum,
    and mean value, and the first and last title

 -help OR -usage
    Print help output

  -StandardInput
     Read parameter entries from standard input.
