Camerino, Italy, 9-January-2002

The present 12.2001 version of the GNXAS programs incorporates all the advances of the previous versions (Camerino 3.2001, 9.00 and L'Aquila 2.2000). The new Linux version is compiled using both the 2.2.16 kernel and 2.2.14 kernel while the still available 3.2001 version expiring on December 2002 was compiled using the 2.2.13 kernel . Please note the important changes of the FITHEO program with respect to previous versions. Check the new FITHEO 12.2001 and 9.00 features for more information. Older news containing interesting information about development of the programs are still available.

Camerino, Italy, 24-August-1999

The new 8.99 version of the GNXAS programs includes several corrections and upgrades of the software which can be now more efficiently used on several different platforms including OpenVMS and Linux. In FITHEO spline coefficients can be now used as MINUIT parameters in multi-edge fitting and graphic output has been improved (see new features ). CRYMOL, GNXAS and CONTOUR were also corrected in order to run under VMS operative system. Please note that some four-body GNXAS output signals are not reliable (especially under Linux) and we are working on fixing this problem. The OpenVMS 8.99 version are already available on this site, the updated versions for other platforms will follow in the next days. Check out also the alternative L'Aquila GNXAS site.

Camerino and L'Aquila, Italy, 14-April-1999

Following the requests of many users and friends A. Filipponi spent several days of work to improve the software on different machines that are available to us. The same codes have been compiled on VMS and Unix machines.

The executable are available for down-loading at the web site http://gnxas.unicam.it as gzipped binary files, in particular:

In addition to the version for open-VMS DEC

• gnxas_ov15_a.zip (OpenVMS 1.5)
• gnxas_ov61_a.zip (OpenVMS 6.1)

The programs are now available for

HP-Unix

• gnxas_HP-UX.tar_gz

SunOS

• gnxas_SunOS.tar_gz

DEC-alpha

• gnxas_OSF1.tar_gz

Linux on IBM-compatible PC's

• gnxas_Linux.tar_gz

Changes in the registration procedures:

Both old and new users must be registered using the

• official form .

UNIX

The programs for Unix machines require a personal or site-dependent password-file to run, this will be sent to the users after registration. You can register either as an individual or as a group, requesting for a machine/cluster license. In the case of individual usage you can install the package in a subdirectory of your account (i.e. ~/gnxas). If several users will be running the programs from the same machine/cluster we recommend to ask for a group license. Detailed information about installation are contained in UNIX installation details .

VMS

Updated programs for OpenVMS alpha and VAX versions are available for all of the registered users (up to April 99). No changes in the authorization codes have been done. Users should wait an e-mail confirmation for the gnxas authorization of their personal nodename and usernames. Program have an expiration date.

WARNING!

The 2.99 version is a beta release! Only a few tests have been done on the present programs. The sources derive mainly from the HP version which has been running at the ESRF for the last 3 years, however, there have been major changes to compile on Linux with g77. The 2.99 version is the result of the efforts of A. Filipponi in adapting the gnxas software to Linux operative systems and is subject to changes correcting bugs or improving the software. Please let us know immediately if you find any relevant difference from previous versions. The new 2.99 version for OpenVMS users is also a beta release. No detailed tests have been performed up to now for the present programs and they should be used with cautions. Users are encouraged to use the latest versions sending us their comments and detailed explanations of errors and bugs. You should be warned, however, that, even if the source codes for various platforms are the same, you should not expect identical results from different machines due to the effect of the numerical accuracy and of the different routes chosen by minimization algorithms used by MINUIT.

• Please read carefully the main new features of 2.99 software.. For any problem please contact:
