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
250<DT>TOF facilities
251<DD>Improve adding multiple histograms by specifying d-min or Q-max in place
252of tof-min; Allow INSTEDIT to be used for TOF instrument parameter files.
253(4/2006, 1.79)
254<DT>MUSTRPLOT
255<DD>Add micro-strain plotting program to menus.
256(4/2006, 1.79)
257
258<DT>Recomputation of Multiplicities
259<DD>EXPGUI can now recompute the multiplicities for a set of atoms. This can be
260done with a button on the edit atoms page and is automatically done when the
261atoms coordinates are changed with a transformation matrix or an origin shift
262as well as prior to a composition computation.
263(2/2006, 1.78)
264<DT>Bug & Cosmetic Fixes
265<DD>Put GSAS into window title
266<BR>rationalize appearance of some labels fields (histogram heading & history)
267<BR>bug: in global setting of phase fractions & ph. frac. damping
268<BR>prevent use of more than 36 bkg parameters in BKGFIT, since that is all GSAS allows
269<BR>fix bug in 2theta max when adding multiple histograms
270(2/2006, 1.78)
271
272<DT>
273Transform Atoms - Origin 1 -> 2
274<DD>
275The option to transform Origin 1 settings to Origin 2 is now provided
276in the windows raised by th "xform atom(s)" button on the phase panel.
277(9/2005, 1.77)
278
279<DT>
280DRAWxtl Export
281<DD>
282DRAWxtl export has been enhanced to display vectors for magnetic phases
283and to launch DRAWxtl directly.
284(9/2005, 1.77)
285
286<DT>Spherical Harmonic Fix
287<DD>In June 2005, GSAS was changed to allow more spherical harmonic terms
288by renaming the CRSxODF records. EXPGUI now converts old records to the
289new format and can read them.
290(9/2005, 1.77)
291
292<DT>Import coordinates from .EXP file
293<DD>Fix bug introduced when new all-in-one Tcl/Tk package was implemented
294(missing package require Tk).
295(9/2005, 1.77)
296
297<DT>Print from LSTVIEW (Unix only)
298<DD>Selected text can be sent to lpr command
299(3/2005, 1.76)
300
301<DT>Misc fixes from RBVD
302<DD>Fix profile 4 labels, add support for #5, add LS Band control, add
303extra digit to PRNT for extra option, note Pawley phase.
304(3/2005, 1.76)
305
306<DT>Prevent use of Zero & SHFT (+ TRANS) parameters together
307<DD>A common GSAS error is to refine a zero correction together with
308the Bragg-Brentano corrections (SHFT & TRANS). When Zero is refined,
309TRANS & SHFT are now turned off and disabled.
310(3/2005, 1.76)
311
312
313<DT>Cleanup/Bug fixes
314<DD>Require BWidget package; provide a clear error message when not found.
315Fix vector access in liveplot (not broken?) & excledt for BLT2.4z.
316More documentation changes.
317(9/2004, 1.75)
318<DT>Installation/instructions
319<DD>New GSAS/EXPGUI packages have been created for
320all platforms using the new Tcl/Tk starkits.
321The installation instructions for Windows, SGI/Linux & Mac OS X have
322been extensively revised.
323(9/2004, 1.74)
324<DT>WINUTILS
325<DD>EXPGUI now can use the WINUTILS or WINEXEC package to run
326GSAS programs in a COMMAND.COM window on Windows-95/-98 and -ME.
327This was needed to update to a newer Tcl/Tk release that fixes
328a hang in -XP. Note that WINUTILS & WINEXEC are not used
329in -NT/-2000/-XP.
330Also, misc "package require" etc. to use Tcl/Tk Starkit (all platforms).
331(9/2004, 1.74)
332<DT>Coordinate export to DRAWXTL
333<DD>new export routine creates a .STR file for the
334very nice
335<A HREF="http://www.lwfinger.net/drawxtl/">DRAWXTL</A> visualization program.
336(9/2004, 1.74)
337<DT>Coordinate export to CIF
338<DD>new export routine creates a bare-bones CIF file with coordinates
339for a phase.
340(9/2004, 1.73)
341<DT>Fix non-ASCII character bug
342<DD>A bug was fixed that previously allowed EXPGUI to place
343non-ASCII characters into a .EXP file. GSAS could not read these files.
344This may not address every possible way this could happen (I was bit
345by this before, see note on v1.64), but should catch a lot more of these
346problems.
347(9/2004, 1.73)
348
349<DT>zoom fixes for BLT2.4z
350<DD>BLT 2.4z changes, yet again the binding for zooming; EXCLEDT & BKGEDIT
351were updated to address this. The best cure for this is probably to not
352use the mouse buttons for other purposes.
353(5/2004, 1.72)
354<DT>LIVEPLOT ignore bad element attributes
355<DD>if a bad color value, etc. was saved for liveplot, the program would
356not start; this has been fixed.
357(5/2004, 1.72)
358<DT>Open Console
359<DD>An "open console" command has been added to the help menu in EXPGUI,
360LSTVIEW, LIVEPLOT, BKGFIT, WIDPLT & ABSPLT to help with debugging
361(5/2004, 1.72)
362
363<DT>Misc bug fixes (from Lachlan)
364<DD>make sure initial alpha1:2 ratio is 0.5 not 0.0; fix INSTEDIT none button;
365save changes before BKGEDIT.
366(5/2004, 1.71)
367<DT>LIVEPLOT
368<DD>Add (obs-calc)/sigma plotting to LIVEPLOT
369<BR>Use arrow keys to move zoom region around (convenient!)
370(4/2004, 1.71)
371<DT>Fox export
372<DD>Flag origin 2 space groups for FOX XML output
373(4/2004, 1.71)
374<DT>INSTEDIT bug
375<DD>Add ITYP line to instrument parameter file
376(4/2004, 1.71)
377<DT>Scan plot zoom
378<DD>The zoom region in LIVEPLOT, EXCLEDT & BKGEDIT can be moved around
379with the arrow keys (convenient!)
380(4/2004, 1.71)
381
382<DT>Customization for OS X
383<DD>On OS X, EXPGUI will set app & define icon for .EXP files
384(1/2004, 1.69)
385
386<DT>CIF updates
387<DD>Update CIF codes to use different indexing scheme for dictionaries
388(12/2003, 1.68)
389
390<DT>reflection mark bug in excledt
391<DD>Fix edit broken close button for edit reflection marks in excledt; remove
392unneeded phases from option list; implement reflection mark shortcuts [press
3931 for phase 1,...]
394(12/2003, 1.65)
395
396<DT>Fix "Chinese date bug"
397<DD>Windows computers set to operate with Chinese inserted timezone reference
398into .EXP history record with chinese characters; this made .EXP file invalid
399within GSAS. The time zone is no longer recorded.
400(11/2003, 1.64)
401
402<DT>Change "Use new name" for archived .EXP files
403<DD>If you are reloading an archived .EXP file, you can copy it to be the
404latest version of the current .EXP file, or supply a new name. Previously,
405it saved the current file under a new name -- what was I thinking then?
406(11/2003, 1.64)
407
408<DT>OS X compatible
409<DD>This version of EXPGUI runs under Macintosh OS X(!)
410(11/2003, 1.64)
411

413<DD>This option allows two or more "banks" of data to be read in a single
414pass for use with multibank diffractometers
415(8/2003, 1.62)
416
417<P>
418<DT>Instrument parameter file editor
419<DD>This is used to modify and create instrument parameter files
420(5/2003, 1.61)
421
422<DT>Absorption correction big fix.
423<DD>The problem where a change made by EXPGUI causes EXPEDT to garble
424the ABSCOR record has been located and fixed, finally. Thanks are due to
425detailed bug reports from 3 different people, so that this bug could be
426tracked down!
427(5/2003, 1.61)
428
429
430<DT>Change .gsas_config to c:\gsas.config on windows
431<DD>The name ~/.gsas_config makes sense in UNIX but is clumsy in Windows
432(5/2003, 1.61)
433
434<DT>LIVEPLOT export
435<DD>Liveplot now exports data to FOX and .CSV files (to produce publication
436quality graphics).
437(4/2003, 1.60)
438
439<DT>Export to FOX
440<DD>EXPGUI can now export coordinates & raw data to FOX
441(Free Objects for Xtallography, objcryst.sourceforge.net)
442via XML.
443(9/2002, 1.58) & 
444(4/2003, 1.60)
445
446<DT>TOF bug fixes, POWPREF nagging
447<DD>The "add histogram", EXCLEDT and BKGEDIT sections were reworked to
448correct errors in handling TOF datasets. EXPGUI flags changes that
449would require POWPREF to be run before GENLES and warns if POWPREF is not
450run.
451(4/2003, 1.60)
452
453<DT>GSAS2CIF, FillCIF & CIFSelect
454<DD>The GSAS2CIF program has been rewritten, the FillCIF utility
455has been created to edit the new CIF templates
456and the new CIFSelect utility is provided to edit distance & angle publication
457flags. A new <a href="gsas2cif.html">GSAS2CIF web page</A> has been created to describe the process.
458(9/2002, 1.58)
459
460
461<DT>Fix profile constraint bug
462<DD>Profile constraints now must have a histogram & phase selected;
463defaults are used, where appropriate.
464(9/2002, 1.58)
465
466<DT>Profile Constraint bug fixes
467<DD>The cancel button is fixed & the continue button for new constraints
468works only when 1 or more terms are selected.
469(7/2002, 1.56)
470
471<DT>Show cursor position in LIVEPLOT
472<DD>Cursor position can optionally be displayed in LIVEPLOT/BKGEDIT
473(press "L" for live cursor).
474(2/2002, 1.55)
475
476<DT>Bug fixes

484
485<DT>Coordinate Import/Export
486<DD>Export formats can now be added at run-time by writing
487export_*.tcl files. Export to MSI .xtl, SHELX & Platon .spf files
488is now supported.
489<BR>
490Import from .xtl & .spf (PLATON) files. For
491.xtl import, automatically shift Origin 1 to origin 2.
492<BR>
493Better translation/checking of space group names on import. Space groups are
494better checked against spacegroup.ref in import_cif.tcl as was added

582button.
583(9/2001, 1.47)
584
585<DT>
586Histogram flags
587<DD>
588The use/do not use flag for histograms can now be set using a button

598
599<DT>
600Adjustable screen font selection
601<DD>
602Font size can now be selected from a menu. Convenient, as well as
603perhaps improving on utility for folks with visual disabilities.
604The customization discussion in expgui_cfg.html
605now tells how to do override the default families & relative sizes.
606(9/2001, 1.46)
607
608<DT>
609Add Marquardt damping, LeBail damping to GUI
610<DD>
611These parameters are on "LS Controls" panel, along with
612the convergence parameter. The <a HREF="expgui1.html">documentation for this
613panel</A>
614has also been expanded
615to better explain what these options do. (7/2001, 1.44)
616
617<DT>
618Fixed background points (BKGEDIT)
619<DD>
620Fits a Chebeshev polynomial to a set of fixed points input by a user.
621If need be (not recommended, though) the background points
622can be input to GSAS as fixed background values. (7/2001, 1.44)
623<DT>
624"doc-less" install
625<DD>
626Allow doc web pages to be read from www.ncnr.nist.gov, if not present on
627local system (6/2001, 1.43)
628
629<DT>
630Load archived files (Unix only)
631<DD>
632A convenient way to load archived versions of the .EXP file has been
633added to the EXPNAM command (4/2001, 1.42).
634
635<DT>
636Sort atoms to be added
637<DD>
638A convenient way to sort the atom list (4/2001, 1.42).
639
640<DT>
641WWW links
642<DD>
643Implemented context-sensitive help that brings up web pages
644from local storage. (10/2000, 1.38)
645
646<DT>
647Error reporting
648<DD>
649When an invalid entry is specified, (for example 1..0 is typed, instead
650of 1.0) EXPGUI ignores the entry and (now) it is also displayed in red, to
651flag the error. This only happens for entries on the main panels. For
652entries on modal dialogs (where there a "done" or "keep" button), these
653errors will be reported only when the button is pressed. (10/2000, 1.38)
654
655<DT>
656Import Atoms/Import Phase
657<DD>
658A CIF import routine is now available. (10/2000, 1.38)
659
660<DT>
661"Non-shell" version of EXPGUI
662<DD>
663EXPGUI has two functions, 1) to act as a "shell" that calls the
664various GSAS programs, and 2) to edit the .EXP file. For use with
665MacGSAS (and possibly the standard Win-95 GSAS shell), it is possible
666to turn off the "shell" features -- by calling EXPGUI with the argument
667-noshell or /noshell or by setting environment variable EXPGUI_NOSHELL to 1.
668This mode has not yet been tested and is not expected to
669be needed due to the OS X release. (10/2000, 1.36)
670
671<DT>
672NIST accessibility requirement
673<DD>
674NIST requires that all images in WWW pages have an ALT= tag included.
675This has been done on all the documentation HTML pages, despite the
676fact that (in this case) it adds no new content for anyone.
677
678<DT>
679Change space group/Import from file
680<DD>
681A mechanism where one can specify a new space group, cell,
682and reinput all atoms for the phase (to get site syms correct). One can
683keep the old atoms for the phase or replace them. It is possible
684to do this manually or with a file import capability.
685At present the only file type accepted is
686the .CEL format from PowderCell. New format filters can be "dropped" in
687place. (8/2000, 1.33)
688
689<DT>
690Import Atoms/Import Phase
691<DD>
692This appears on the add atoms & add phase dialogs and draws on the above.

694
695<DT>
696Transform Atoms
697<DD>
698There is now a "xform atom(s)" button on the phase panel that
699can be used to transform coordinates,
700globally set the occupancy & Uiso and switch atoms between
701iso/aniso and erase selected groups of atoms
702(8/2000, 1.31)
703
704<DT>
705Delete phases
706<DD>
707Work around -- change phase flags on the histogram page (appears when 2+ phases
708present).
