Release Name: xtal-3.7.2

Notes:
             GNU XTAL SYSTEM RELEASE 3.7.2 

Xtal 3.7.2 is the first release of The Gnu Xtal System. 
Xtal is distributed under the GNU general public License.
See the license for details.
Whats Gnu you may ask? Well, see the change log for that!

3.7.2 is the latest offering in unofficial unsupported Xtal software.

NOTE: Use fix2 for Win32, which apparently didnt shutdown the
dynamically loaded dll tcllib.dll cleanly, as became manifest under Win98.
Also post-last minute changes to OUTSRC to dump Friedels then
trashed the .hkl file when no Friedels were present. Now fixed and
correct ZERR value inserted in SHELX .ins value. Foobah humbug.


              DEPENDENCIES

Xtal should work well/identically under both linux and MS Windows.
Windows support was implemented using the Cygwin build environment,
(thanks guys!) but the xtal binary itself does not maintain any 
Cygwin dependencies i.e. you should not need Cygwin installed to 
run Xtal 3.7.2 in a MS Windows environment.

On the other hand the linux binary version is suffering from 
transitional C-library dependencies. So if the run time loader
complains about missing libc.so libs, you now know why.
Grab the sources and build it yourself!


Xtal also maintains a dependency on Tcl/Tk, and with the inclusion
of a grossly experimental SURFIN program, on OpenGL libraries also.
However, the Tcl/Tk dependence is now customizable to a great extent.
By setting the XTALTCLLIB and XTALTKLIB environment variables you
should be able to select the specific dynamically loaded link library
you wish to use at execution time. In principle any version of 
Tcl/Tk>=8.2 should be perfect. However, having built the xtal binaries
against tcl/tk 8.4, one glitch has manifested when linked against 
tcl8.2 (dll and so). Specifically, the second invokation of an 
Xtal windowing program fails to create a new Tcl interpreter and subsequently
terminates the xtal process. This doesn't occur when linked against 
tcl8.3 or tcl8.4 (dlls and .so), to the best of my limited knowledge.
So I recommend upgrading whatever tcl distribution you have to 8.3 or 
greater ...

Xtal is also dependent on ciftbx2.6.3 
Xtal is also dependent on the Togl Tcl/Tk OpenGL interface
Xtal is also dependent on the atomic scattering data of Prof. S. Sasaki

Thanks to those authors and software's developers for permitting such
useful data and programs to be included with this distribution.


              PLATFORM SPECIFIC BUILD PROBLEMS

It has only really been tested under linux and MS windows, and even there
somewhat sparingly ...

On other platforms, you will inevitable have to edit the makefiles to
accomodate recent changes.

If you try to build it on an Alpha True64 Unix platform, watch out for 
mx30.r. It needs special compiler options to reverse the endianness 
of the file reading, considered optimal by the Wien2k folks ... 
(Most people needn't bother about this!).



              PLATFORM SPECIFIC INSTALLATION PROBLEMS

Probably the primary rationale for this Xtal release was to provide an
interface to WinGX and its vast array of other supported softwares
within the MS windows environment. Louis Farrugia very kindly helped
out with advice, examples and code. Installation works pretty much
like this:

Xtal must be installed first. Especially, Xtal must be installed with the
XTALHOME/XTALTCLLIB etc variables set globally via the MS windows menu 
      Start->Control Panel->System->... 
After Xtal is installed WinGX should be installed/re-installed. 
If WinGX is re-installed, it does not rescan the file system for new supported
programs unless the original wingx.ini file is deleted, by you. 
So you should definitely do that.

WinGX operates assuming that a common parent folder (directory) exists 
containing separate folders for every jobname/experiment/compound being studied.
Each "jobname" folder is a WinGX "working directory" for that job. 
To run an Xtal job from within WinGX, a subfolder called "xtal" will be created
within each WinGX "job" folder (as the need arises, and if you haven't already 
created it yourself) and all Xtal processes invoked from WinGX are run there. 
All WinGX xtal jobs are invoked with the default compid, i.e. "compid xtal", 
so if you start mixing different Xtal studies in the same directory, you're 
headed for trouble!


WinGX comes with slots for 20 customizable Xtal commands. You can control their 
functionality by editing the C:\wingx\files\xtalcom.dat file.
Unfortunately the biggest hurdle for existing Xtal users will be 
migrating their xtal data to WinGX .ins format initialy, in order to 
activate the WinGX Refine->Xtal command functionality.

The new Xtal program OUTSRC should be useful in this respect. It exports Xtal 
data into SHELX format .ins and .hkl files. You will however need to copy it 
back up to the WinGX "job" folder, and no doubt rename the files to job.ins and 
job.hkl before exporting back to xtal to activate the 
WinGX Refine->xtal functionality. 
 

And remember, in any graphics modes, check the NUM-LOCK key because its an
X11 mouse click modifier and nothing works when the lock is engaged!


              DISCLAIMER

The Gnu Xtal System, 3.7.2, is covered under the Gnu General Public License.
It may not work at all. If it doesn't, please fix it and submit patches 
using the resources at http://xtal.sourceforge.net/


              THANKS

Thanks also to you the potential users, for testing this software.
It would be gratifying to to know that it was being used and that the effort
wasn't entirely wasted. It's hoped also that some folk might even 
be inclined to actively participate in the ongoing development of Xtal. 
It could use some new, dedicated, management ...


Best regards,

the team.





Changes:
This is the CVS changelog since 3.7.1 

In a nutshell:

The new DocBook manual has been added to the distribution. 
Now there is a PDF version as well as HTML.
A few new programs were added, mostly irrelevant to existing users.
The exceptions are:
ADDREF now culls fractional indices which arise in transformations.
PLOTX can write to a specific filename
OUTSRC and SHELIN were added/modified for WinGX/SHELX compatability.
DIFDAT now supports the SHELX format .hkl file and Rigaku RAPID f2plus
       (stored as f^2 and not irel)
EXPAND was added to aid in symmetry transformations
SURFIN may be useful for quick and dirty difference density checks.
POWGEN calculates powder patterns from frel and fcal
STARTX now finds absorption and dispersion factors automatically 
(Dummy atom types can be entered with Z=0 and void weight.)
CIFIO cifout has been fiddled a bit to improve cifreq file support
Hopefuly in conjunction with ADDREF and SORTRF some CIF file problems
with absolute structure have been circumvented.
