Prerequisites

  

To be able to run FIT2D the following tasks must have been fulfilled:

Installation:  FIT2D since Version 7.0 is a single executable which does not depend on any other files, although a PostScript version of this reference manual may also be useful, as might be the introductory manual: ``FIT2D: An Introduction and Overview'' (both these manuals are now available as web pages).[*]. FIT2D executables    are available for most workstation systems and can be obtained from the world-wide web . The FIT2D  home page  URL  is:
http://www.esrf.fr/computing/expg/subgroups/data_analysis/FIT2D

From the home page links to installation documentation, executables, and user and reference manuals are available. With a minimum of computer knowledge you should be able to obtain and set-up FIT2D yourself. Otherwise ask your system administrator for help.

On Unix systems it is generally necessary to set the ``executable bit''. Assuming the FIT2D executable has been copied to a file named fit2d, this can be achieved with the following Unix command:

chmod +x fit2d

Environment Variables:  On Unix systems The following environment variable needs to be defined:

DISPLAY   As with all X-11 programs the environment variable DISPLAY needs to be set to your X-11 display. Normally this will be defined automatically, but sometimes it may be necessary to define or re-define this variable manually. e.g. Using the ``C'' shell or (better) the ``T'' shell with a workstation called experiment1 the following command could be typed on the ``T'' shell command line:
setenv DISPLAY experiment1:0

FIT2D_KEY   variable needs to be set to an individually determined code: ``the software key''. This is only necessary outside of the ESRF, and not on ESRF computer systems. For external users an e-mail message will be with the value of the individual code (key value) and instructions on how to set it.

The current ``values'' of the environment variables may be checked by using the ``C''/``TC'' shell command printenv.
