        Using HDF at NCSA
*****************************

 HDF is installed on various systems at NCSA.  The following is a list 
of directories in which HDF is installed on different systems:


       Cray-2:      /usr/local/apps/hdf
       Cray-XMP:    /usr/local/apps/hdf
       Suns:        /soft/hdf
       Medusa:      /usr/hdf
       Replicant:   /usr/hdf

The current version of HDF will be in that directory and its 
subdirectories.

In the bin/ directory you will find several HDF utilities, such as:

   hdfls - a utility to display information about the contents of an            
HDF file.

   hdfrseq - a utility to display a raster 8 bit image remotely using
              the NCSA Interactive Color Raster protocol.

   hdftor8 - a utility to convert an HDF raster 8 bit image into a raw
              raster image.

   r8tohdf - a utility to convert a raw raster image to an HDF raster 8
              bit image.

   hdfcomp - a utility to change the compression scheme used for 8-bit
             raster images in HDF files.

If you execute any of these commands with no parameters, it will display 
the list of acceptable parameters.

In the doc/ directory you will find files containing the HDF 
documentation.

In the examples/ directory you will find example codes using HDF. The 
example codes should be self explanatory.

In the include/ directory you will find the necessary include files for 
use in your own programs that link with the HDF library.

In the lib/ directory you will find the HDF library which contains the 
necessary subroutines for developing your own HDF applications.

In the src/ directory you will find the source for all of the HDF 
utilities and library.

If you have any questions, please contact the NCSA Consulting Office.
