**   NOP INSTALLATION NOTES - March 21st 2002   **
**************************************************


+ General information and known bugs:
-------------------------------------

The present version is a Beta version. This means that you would find typing errors and some bugs there because some parts are still under final development. 

Known problems which should be solved very rapidly are the following:
* A big issue is the energy scan process of NCrystal application which not running by now. It runs but without producing proper datafile output. In the same aplication results are still shown in terms of X-Rays labels. That means that plots are drawn with "s-polarisation" and "p-polarisation" labels. Simply, don't mind about this. The code is showing the good result, the one for neutrons, in both columns which are strictly identical. 
* A graphical bug of Xplot can show an unwanted extra point at 0.0 X-coordinate. We are also pushing hard to understand why. It's ennoying if you want to plot something but not a problem as soon as you just want to take a look to the result and not want to perform graphical artistic view of it !
* XInpro which is exactly the same as the one in XOP was let in order to calculate some important inputs for XCrystal (I'm thinking at the Debye Waller coefficient for exemple). If you use it you have to take care about energy unit used in it. It actualy uses eV unit for photons. That means that if you have a neutron energy you may first convert it into wavelength and then transform this wavelength into the equivalent eV for a photon.
For example, for photons : E(ev)=12398.4/lambda(A) 
and for neutrons : E(mili-eV)=0.0818042/(lambda(A)^2)


+ Installation - Windows:
-------------------------

1) unzip the NOPBetaWin.zip file.

2) copy xop.ini file under either the WINDOWS or WINNT directory.

3) copy all other files in the directory of your choise.

4) open xop.ini file and change paths according to the directory you choose for NOPBeta.

5) double click on xopexec_x86.exe to run the code.

That's all !

6) Optionnal : if you create a shortcut to your desktop of the applicaton you can change the XOP icon to the temporary one for NOP which is located in the "ifc" directory (NOPico.ico)


+ Installation - Linux (Unix ?):
--------------------------------

0) this was not tested under Unix yet. It works on Linux, any try feedback about Unix systems is welcommed at this point !

1) untar the NOPBetaLin.tar.gz or NOPBetaLin.tar.bz2 file.

2) copy all files in the directory of your choise.

4) open xop file and change paths according to the directory you choose for NOPBeta.

5) run ./xop to run the code (you can place a link in the /bin directory is desired).

That's all !
