UNIX Extensions for XOP 2.0 (Installation notes)
               ================================================

IMPORTANT: The installation of XOP extensions requires a previous 
	   installation of the main XOP

XAID [XAFS toolbox]
-------------------
  1) Download the file xaid1.2.tar.Z to your main XOP directory
  2) Execute:
     zcat xaid1.2.tar.Z | tar xvf -
  3) Start xaid by entering at the unix prompt:
      xop xaid

      Note: The XAID installation package does not contain the DABAX
      files containing the EXAFS and XANES experimental database.
      If you want to install them, just copy into your
      $XOP_HOME/data/dabax directory the (big) files:

      ../../DabaxFiles/XAFS_DATA_EXAFS_CHI.dat
      ../../DabaxFiles/XAFS_DATA_EXAFS_CHI.HIdl
      ../../DabaxFiles/XAFS_DATA_XANES.dat
      ../../DabaxFiles/XAFS_DATA_XANES.HIdl


TOPO [analysis on profiles and surfaces by Windt]
-------------------------------------------------
  1) Download the file topo2.04.tar.Z to your main XOP directory
  2) Execute:
     zcat topo2.04.tar.Z | tar xvf -
  3) Start topo by entering at the unix prompt:
      xop topo4xop

IMD [Multilayers by Windt]
--------------------------
  1) Download the file imd4.1.tar.Z to your main XOP directory
  2) Execute:
     zcat imd4.1.tar.Z | tar xvf -
  3) Start imd by entering at the unix prompt:
      xop imd4xop

SHADOWVUI [Visual user interface to the x-ray tracing program SHADOW)
 --------------------------------------------------------------------
  1) Download the file shadowvui1.0Beta3.tar.Z to your main 
     XOP directory
  2) Execute:
     zcat shadowvui1.0Beta3.tar.Z | tar xvf -
  3) Install SHADOW for your computer platform. Files for SHADOW
     can be downloaded from: 
         http://www.nanotech.wisc.edu/shadow
    (alternatively see http://www.esrf.fr/computing/scientific/raytracing/)
    (to make its downloading easier, the files for installing SHADOW 2.3.2
     under few Unix platforms are in the ./SHADOW directory).
  4) Edit the files .shadowrc and .shadowrc.sh in the directory where
     you installed SHADOW.
	4.1) Set the SHADOW_ROOT to your particular installation directory
	4.2) VERY IMPORTANT: Set a new environment variable (add new line(s)):
	 	<> in file .shadowrc:
	     	setenv SHADOW_ENV_FILE  "/tmp/shadow-env-${USER}" 
	 	<> in file .shadowrc.sh:
	     	SHADOW_ENV_FILE="/tmp/shadow-env-${USER}"
		export SHADOW_ENV_FILE
  5) Edit the file 
	$XOP_HOME/extensions/shadowvui/data/shadowvui_preferences.pro
	and customize the variables in the UNIX block (see instructions
	therein).
 
  6) Start shadowvui by entering
      xop shadowvui

  NOTE: The SHADOW version 2.3.2 contains a bug in the wiggler source and
      crashes the program. Older versions may work.
