40<H2>Requested EXPGUI improvements</H2><DL>
41The suggested improvements obtained from EXPGUI users are listed here.
42Prioritization is based in part on input from users, from back when
43EXPGUI development was supported by NIST via ATP intramural program.
44At present EXPGUI development is progressing slowly, since the work
45is not funded.
46<P>
47In the list below, dates for requests are noted in parenthesis when known.
48Additional suggestions and input on priorities are welcome; send them to
49the author of EXPGUI,

241<H2>RECENT ADDITIONS TO EXPGUI</H2><DL>
242Additional features & fixes added to EXPGUI since mid-2000 are listed here,
243with an approximate date the features were added and the EXPGUI version
244where the feature was added. This list includes only the more significant
245changes.
246For a complete list of all changes for the source files
247see <A HREF="revlog.html">the EXPGUI Revision log.</A>
248<P>
249<DT>Import pdCIF data
250<DD>EXPGUI can now read powder CIF data and rewrite it as
251  GSAS .fxye (1 line per file) data. For CW data only.
252(4/2006, 1.83)
253<DT>DISAGL export
254<DD>Add button to select distances from 1 phase and copy to Windows clipboard
255  to interface with Andrew Will's VaList program (not yet tested).
256(4/2006, 1.83)
257<DT>Bug fixes & cleanup
258<DD>Bugs in EXCLEDT, Import Atoms, etc; relabel many buttons for better
259  consistency and to be more conventional.
260(4/2006, 1.83)
261<DT>EXPGUI macros added
262<DD>EXPGUI can record nearly all actions into a macro file. The macro file
263  can be "replayed" to repeat those actions on a new experiment. Macro
264  files can replayed a line at a time or can be executed all at once.
265  Tcl commands
266  can be introduced into a macro file so that programming can be done
267  with macro files. Misc changes to suit this such as turn of prompt when
268  running GSAS programs; run GSAS programs w/o terminal windows.
269(4/2006, 1.82)
270<DT>User error checking
271<DD>Check for final R in space group name for R space groups in
272  rhombohedral settings.
273(4/2006, 1.82)
274<DT>Lattice parameter entry
275<DD>Unit cell type now constrains the number of lattice parameters that can be
276  entered.
277(4/2006, 1.82)
278<DT>Import diffractometer constants
279<DD>Diffractometer constants can be read from a GSAS .EXP file into INSTEDIT.
280(4/2006, 1.82)
281<DT>Minor changes
282<DD>fix grace export, spelling on convergence, warn on windows if COMSPEC
283  (cmd.exe location) is not defined.
284(4/2006, 1.81)
285<DT>Minor changes
286<DD>Add gsas2map, remove now defunct background #3, fix Q conversion in background

292(4/2006, 1.79)
293<DT>MUSTRPLOT
294<DD>Add micro-strain plotting program to menus.
295(4/2006, 1.79)
296
297<DT>Recomputation of Multiplicities
298<DD>EXPGUI can now recompute the multiplicities for a set of atoms. This can be
299done with a button on the edit atoms page and is automatically done when the
300atoms coordinates are changed with a transformation matrix or an origin shift
301as well as prior to a composition computation.
302(2/2006, 1.78)
303<DT>Bug & Cosmetic Fixes
304<DD>Put GSAS into window title
305<BR>rationalize appearance of some labels fields (histogram heading & history)
306<BR>bug: in global setting of phase fractions & ph. frac. damping
307<BR>prevent use of more than 36 bkg parameters in BKGFIT, since that is all GSAS allows
308<BR>fix bug in 2theta max when adding multiple histograms
309(2/2006, 1.78)
310
311<DT>
312Transform Atoms - Origin 1 -> 2
313<DD>
314The option to transform Origin 1 settings to Origin 2 is now provided
315in the windows raised by th "xform atom(s)" button on the phase panel.
316(9/2005, 1.77)
317
318<DT>
319DRAWxtl Export
320<DD>
321DRAWxtl export has been enhanced to display vectors for magnetic phases
322and to launch DRAWxtl directly.
323(9/2005, 1.77)
324
325<DT>Spherical Harmonic Fix
326<DD>In June 2005, GSAS was changed to allow more spherical harmonic terms
327by renaming the CRSxODF records. EXPGUI now converts old records to the
328new format and can read them.
329(9/2005, 1.77)
330
331<DT>Import coordinates from .EXP file
332<DD>Fix bug introduced when new all-in-one Tcl/Tk package was implemented

335
336<DT>Print from LSTVIEW (Unix only)
337<DD>Selected text can be sent to lpr command
338(3/2005, 1.76)
339
340<DT>Misc fixes from RBVD
341<DD>Fix profile 4 labels, add support for #5, add LS Band control, add
342extra digit to PRNT for extra option, note Pawley phase.
343(3/2005, 1.76)
344
345<DT>Prevent use of Zero & SHFT (+ TRANS) parameters together
346<DD>A common GSAS error is to refine a zero correction together with
347the Bragg-Brentano corrections (SHFT & TRANS). When Zero is refined,
348TRANS & SHFT are now turned off and disabled.
349(3/2005, 1.76)
350
351
352<DT>Cleanup/Bug fixes
353<DD>Require BWidget package; provide a clear error message when not found.
354Fix vector access in liveplot (not broken?) & excledt for BLT2.4z.
355More documentation changes.
356(9/2004, 1.75)
357<DT>Installation/instructions
358<DD>New GSAS/EXPGUI packages have been created for
359all platforms using the new Tcl/Tk starkits.
360The installation instructions for Windows, SGI/Linux & Mac OS X have
361been extensively revised.
362(9/2004, 1.74)
363<DT>WINUTILS
364<DD>EXPGUI now can use the WINUTILS or WINEXEC package to run
365GSAS programs in a COMMAND.COM window on Windows-95/-98 and -ME.
366This was needed to update to a newer Tcl/Tk release that fixes
367a hang in -XP. Note that WINUTILS & WINEXEC are not used
368in -NT/-2000/-XP.
369Also, misc "package require" etc. to use Tcl/Tk Starkit (all platforms).
370(9/2004, 1.74)
371<DT>Coordinate export to DRAWXTL
372<DD>new export routine creates a .STR file for the
373very nice
374<A HREF="http://www.lwfinger.net/drawxtl/">DRAWXTL</A> visualization program.
375(9/2004, 1.74)
376<DT>Coordinate export to CIF
377<DD>new export routine creates a bare-bones CIF file with coordinates
378for a phase.
379(9/2004, 1.73)
380<DT>Fix non-ASCII character bug
381<DD>A bug was fixed that previously allowed EXPGUI to place
382non-ASCII characters into a .EXP file. GSAS could not read these files.
383This may not address every possible way this could happen (I was bit
384by this before, see note on v1.64), but should catch a lot more of these
385problems.
386(9/2004, 1.73)
387
388<DT>zoom fixes for BLT2.4z
389<DD>BLT 2.4z changes, yet again the binding for zooming; EXCLEDT & BKGEDIT
390were updated to address this. The best cure for this is probably to not
391use the mouse buttons for other purposes.
392(5/2004, 1.72)
393<DT>LIVEPLOT ignore bad element attributes
394<DD>if a bad color value, etc. was saved for liveplot, the program would
395not start; this has been fixed.
396(5/2004, 1.72)
397<DT>Open Console
398<DD>An "open console" command has been added to the help menu in EXPGUI,
399LSTVIEW, LIVEPLOT, BKGFIT, WIDPLT & ABSPLT to help with debugging
400(5/2004, 1.72)
401
402<DT>Misc bug fixes (from Lachlan)
403<DD>make sure initial alpha1:2 ratio is 0.5 not 0.0; fix INSTEDIT none button;
404save changes before BKGEDIT.
405(5/2004, 1.71)
406<DT>LIVEPLOT
407<DD>Add (obs-calc)/sigma plotting to LIVEPLOT
408<BR>Use arrow keys to move zoom region around (convenient!)
409(4/2004, 1.71)
410<DT>Fox export
411<DD>Flag origin 2 space groups for FOX XML output
412(4/2004, 1.71)
413<DT>INSTEDIT bug
414<DD>Add ITYP line to instrument parameter file
415(4/2004, 1.71)
416<DT>Scan plot zoom
417<DD>The zoom region in LIVEPLOT, EXCLEDT & BKGEDIT can be moved around
418with the arrow keys (convenient!)
419(4/2004, 1.71)
420
421<DT>Customization for OS X
422<DD>On OS X, EXPGUI will set app & define icon for .EXP files
423(1/2004, 1.69)
424
425<DT>CIF updates
426<DD>Update CIF codes to use different indexing scheme for dictionaries
427(12/2003, 1.68)
428
429<DT>reflection mark bug in excledt
430<DD>Fix edit broken close button for edit reflection marks in excledt; remove
431unneeded phases from option list; implement reflection mark shortcuts [press
4321 for phase 1,...]
433(12/2003, 1.65)
434
435<DT>Fix "Chinese date bug"
436<DD>Windows computers set to operate with Chinese inserted timezone reference
437into .EXP history record with chinese characters; this made .EXP file invalid
438within GSAS. The time zone is no longer recorded.
439(11/2003, 1.64)
440
441<DT>Change "Use new name" for archived .EXP files
442<DD>If you are reloading an archived .EXP file, you can copy it to be the
443latest version of the current .EXP file, or supply a new name. Previously,
444it saved the current file under a new name -- what was I thinking then?
445(11/2003, 1.64)
446
447<DT>OS X compatible
448<DD>This version of EXPGUI runs under Macintosh OS X(!)
449(11/2003, 1.64)

455
456<P>
457<DT>Instrument parameter file editor
458<DD>This is used to modify and create instrument parameter files
459(5/2003, 1.61)
460
461<DT>Absorption correction big fix.
462<DD>The problem where a change made by EXPGUI causes EXPEDT to garble
463the ABSCOR record has been located and fixed, finally. Thanks are due to
464detailed bug reports from 3 different people, so that this bug could be
465tracked down!
466(5/2003, 1.61)
467
468
469<DT>Change .gsas_config to c:\gsas.config on windows
470<DD>The name ~/.gsas_config makes sense in UNIX but is clumsy in Windows
471(5/2003, 1.61)
472
473<DT>LIVEPLOT export
474<DD>Liveplot now exports data to FOX and .CSV files (to produce publication
475quality graphics).
476(4/2003, 1.60)
477
478<DT>Export to FOX
479<DD>EXPGUI can now export coordinates & raw data to FOX
480(Free Objects for Xtallography, objcryst.sourceforge.net)
481via XML.
482(9/2002, 1.58) & 
483(4/2003, 1.60)
484
485<DT>TOF bug fixes, POWPREF nagging
486<DD>The "add histogram", EXCLEDT and BKGEDIT sections were reworked to
487correct errors in handling TOF datasets. EXPGUI flags changes that
488would require POWPREF to be run before GENLES and warns if POWPREF is not
489run.
490(4/2003, 1.60)
491
492<DT>GSAS2CIF, FillCIF & CIFSelect
493<DD>The GSAS2CIF program has been rewritten, the FillCIF utility
494has been created to edit the new CIF templates

564
565<DT>LSTVIEW enhancements<DD>
566LSTVIEW can now be used to plot R-factors as a function of the

620It is now possible to set them up in EXPEDT using the "add histogram"
621button.
622(9/2001, 1.47)
623
624<DT>
625Histogram flags
626<DD>
627The use/do not use flag for histograms can now be set using a button

639Adjustable screen font selection
640<DD>
641Font size can now be selected from a menu. Convenient, as well as
642perhaps improving on utility for folks with visual disabilities.
643The customization discussion in expgui_cfg.html
644now tells how to do override the default families & relative sizes.
645(9/2001, 1.46)
646
647<DT>
648Add Marquardt damping, LeBail damping to GUI
649<DD>
650These parameters are on "LS Controls" panel, along with
651the convergence parameter. The <a HREF="expgui1.html">documentation for this
652panel</A>
653has also been expanded
654to better explain what these options do. (7/2001, 1.44)
655
656<DT>
657Fixed background points (BKGEDIT)
658<DD>
659Fits a Chebeshev polynomial to a set of fixed points input by a user.
660If need be (not recommended, though) the background points
661can be input to GSAS as fixed background values. (7/2001, 1.44)
662<DT>
663"doc-less" install
664<DD>

683from local storage. (10/2000, 1.38)
684
685<DT>
686Error reporting
687<DD>
688When an invalid entry is specified, (for example 1..0 is typed, instead
689of 1.0) EXPGUI ignores the entry and (now) it is also displayed in red, to
690flag the error. This only happens for entries on the main panels. For
691entries on modal dialogs (where there a "done" or "keep" button), these
692errors will be reported only when the button is pressed. (10/2000, 1.38)
693
694<DT>
695Import Atoms/Import Phase
696<DD>
697A CIF import routine is now available. (10/2000, 1.38)
698
699<DT>
700"Non-shell" version of EXPGUI
701<DD>
702EXPGUI has two functions, 1) to act as a "shell" that calls the
703various GSAS programs, and 2) to edit the .EXP file. For use with
704MacGSAS (and possibly the standard Win-95 GSAS shell), it is possible
705to turn off the "shell" features -- by calling EXPGUI with the argument
706-noshell or /noshell or by setting environment variable EXPGUI_NOSHELL to 1.
707This mode has not yet been tested and is not expected to
708be needed due to the OS X release. (10/2000, 1.36)
709
710<DT>
711NIST accessibility requirement
712<DD>
713NIST requires that all images in WWW pages have an ALT= tag included.
714This has been done on all the documentation HTML pages, despite the
715fact that (in this case) it adds no new content for anyone.
716
717<DT>
718Change space group/Import from file
719<DD>
720A mechanism where one can specify a new space group, cell,
721and reinput all atoms for the phase (to get site syms correct). One can
722keep the old atoms for the phase or replace them. It is possible
723to do this manually or with a file import capability.
724At present the only file type accepted is
725the .CEL format from PowderCell. New format filters can be "dropped" in
726place. (8/2000, 1.33)
727
728<DT>
729Import Atoms/Import Phase

731This appears on the add atoms & add phase dialogs and draws on the above.
732(8/2000, 1.33)
733
734<DT>
735Transform Atoms
736<DD>
737There is now a "xform atom(s)" button on the phase panel that
738can be used to transform coordinates,
739globally set the occupancy & Uiso and switch atoms between
740iso/aniso and erase selected groups of atoms
741(8/2000, 1.31)
742
743<DT>
744Delete phases
745<DD>
746Work around -- change phase flags on the histogram page (appears when 2+ phases
747present).
