Information for installing:

Cornean: Cornea Topography Analysis System, ver. 1.0
(c) J. S. Marron and N. Locantore, 1998
Department of Statistics, University of North Carolina

This is intended for MATLAB 5, Windows 95

1.  Copy the Cornean Folder (and subfolders) into the 
  Matlab folder.

2.  Copy the file startup.m into the \matlab\toolbox\local
  folder.

3.  Start matlab (Cornean should be automatically started).

4.  To work with a new image:

  a.  Copy the .xla, .zla, .tla files to the folder
     \matlab\cornean\indata

  b.  Type the file prefix into the window in the main menu




Anticipated Possible Problems and Solutions:

I.  Error message in matlab window, saying can't find files.
  Solution:  paths are wrong, so fix by editing variables in 
      file cornean.m.  In particular change:
        RFILESUF
	HFILESUF
	CFILESUF
	INDATPATH
	FEATMPATH
      as needed.
  Caution 1: do NOT change INFILESTR, as this gets read from 
                    the main menu.
  Caution 2: makes changes only in the block: 
         elseif ipath == 3;   % file path for large memory PC


II.  matlab window shows an "OUT OF MEMORY" message.
  Solution:  problem is this machine doesn't have enough memory.
      Quick fix is a smaller value of NMAX (number of Zernike 
      columns being used).  This is done by editing cornean.m,
      and changing one of two things:
        (a)  the variable ipath can be set to 1 (this sets NMAX to 5)
        (b)  in the block:
                    elseif ipath == 3;   % file path for large memory PC
             change the value of NMAX to the desired value.
