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

| 234 | <H2>RECENT ADDITIONS TO EXPGUI</H2><DL> |
|---|
| 235 | Additional features & fixes added to EXPGUI since mid-2000 are listed here, |
|---|
| 236 | with an approximate date the features were added and the EXPGUI version |
|---|
| 237 | where the feature was added. This list includes only the more significant |
|---|
| 238 | changes. |
|---|
| 239 | For a complete list of all changes for the source files |
|---|
| 240 | see <A HREF="revlog.html">the EXPGUI Revision log.</A> |
|---|
| 241 | <P> |
|---|
| 242 | <DT>Installation/instructions |
|---|
| 243 | <DD>New GSAS/EXPGUI packages have been created for |
|---|
| 244 | all platforms using the new Tcl/Tk starkits. |
|---|
| 245 | The installation instructions for Windows, SGI/Linux & Mac OS X have |
|---|
| 246 | been extensively revised. |
|---|
| 247 | <DT>WINUTILS |
|---|
| 248 | <DD>EXPGUI now can use the WINUTILS or WINEXEC package to run |
|---|
| 249 | GSAS programs in a COMMAND.COM window on Windows-95/-98 and -ME. |
|---|
| 250 | This was needed to update to a newer Tcl/Tk release that fixes |
|---|
| 251 | a hang in -XP. Note that WINUTILS & WINEXEC are not used |
|---|
| 252 | in -NT/-2000/-XP. |
|---|
| 253 | Also, misc "package require" etc. to use Tcl/Tk Starkit (all platforms). |
|---|
| 254 | (9/2004, 1.74) |
|---|
| 255 | <DT>Coordinate export to DRAWXTL |
|---|
| 256 | <DD>new export routine creates a .STR file for the |
|---|
| 257 | very nice |
|---|
| 258 | <A HREF="http://www.nist.gov/cgi-bin/exit_nist.cgi?url= |
|---|
| 259 | http://www.lwfinger.net/drawxtl/">DRAWXTL</A> visualization program. |
|---|
| 260 | (9/2004, 1.74) |
|---|
| 261 | <DT>Coordinate export to CIF |
|---|
| 262 | <DD>new export routine creates a bare-bones CIF file with coordinates |
|---|
| 263 | for a phase. |
|---|
| 264 | (9/2004, 1.73) |
|---|
| 265 | <DT>Fix non-ASCII character bug |
|---|
| 266 | <DD>A bug was fixed that previously allowed EXPGUI to place |
|---|
| 267 | non-ASCII characters into a .EXP file. GSAS could not read these files. |
|---|
| 268 | This may not address every possible way this could happen (I was bit |
|---|
| 269 | by this before, see note on v1.64), but should catch a lot more of these |
|---|
| 270 | problems. |
|---|
| 271 | (9/2004, 1.73) |
|---|
| 272 | |
|---|
| 273 | <DT>zoom fixes for BLT2.4z |
|---|
| 274 | <DD>BLT 2.4z changes, yet again the binding for zooming; EXCLEDT & BKGEDIT |
|---|
| 275 | were updated to address this. The best cure for this is probably to not |
|---|
| 276 | use the mouse buttons for other purposes. |
|---|
| 277 | (5/2004, 1.72) |
|---|
| 278 | <DT>LIVEPLOT ignore bad element attributes |
|---|
| 279 | <DD>if a bad color value, etc. was saved for liveplot, the program would |
|---|
| 280 | not start; this has been fixed. |
|---|
| 281 | (5/2004, 1.72) |
|---|
| 282 | <DT>Open Console |
|---|
| 283 | <DD>An "open console" command has been added to the help menu in EXPGUI, |
|---|
| 284 | LSTVIEW, LIVEPLOT, BKGFIT, WIDPLT & ABSPLT to help with debugging |
|---|
| 285 | (5/2004, 1.72) |
|---|
| 286 | |
|---|
| 287 | <DT>Misc bug fixes (from Lachlan) |
|---|
| 288 | <DD>make sure initial alpha1:2 ratio is 0.5 not 0.0; fix INSTEDIT none button; |
|---|
| 289 | save changes before BKGEDIT. |
|---|
| 290 | (5/2004, 1.71) |
|---|
| 291 | <DT>(obs-calc)/sigma |
|---|
| 292 | <DD>Add (obs-calc)/sigma plotting to LIVEPLOT |
|---|
| 293 | (4/2004, 1.71) |
|---|
| 294 | <DT>Fox export |
|---|
| 295 | <DD>Flag origin 2 space groups for FOX XML output |
|---|
| 296 | (4/2004, 1.71) |
|---|
| 297 | <DT>INSTEDIT bug |
|---|
| 298 | <DD>Add ITYP line to instrument parameter file |
|---|
| 299 | (4/2004, 1.71) |
|---|
| 300 | <DT>Scan plot zoom |
|---|
| 301 | <DD>The zoom region in LIVEPLOT, EXCLEDT & BKGEDIT can be moved around |
|---|
| 302 | with the arrow keys (convenient!) |
|---|
| 303 | (4/2004, 1.71) |
|---|
| 304 | |
|---|
| 305 | <DT>Customization for OS X |
|---|
| 306 | <DD>On OS X, EXPGUI will set app & define icon for .EXP files |
|---|
| 307 | (1/2004, 1.69) |
|---|
| 308 | |
|---|
| 309 | <DT>CIF updates |
|---|
| 310 | <DD>Update CIF codes to use different indexing scheme for dictionaries |
|---|
| 311 | (12/2003, 1.68) |
|---|
| 312 | |
|---|
| 313 | <DT>reflection mark bug in excledt |
|---|
| 314 | <DD>Fix edit broken close button for edit reflection marks in excledt; remove |
|---|
| 315 | unneeded phases from option list; implement reflection mark shortcuts [press |
|---|
| 316 | 1 for phase 1,...] |
|---|
| 317 | (12/2003, 1.65) |
|---|
| 318 | |
|---|
| 319 | <DT>Fix "Chinese date bug" |
|---|
| 320 | <DD>Windows computers set to operate with Chinese inserted timezone reference |
|---|
| 321 | into .EXP history record with chinese characters; this made .EXP file invalid |
|---|
| 322 | within GSAS. The time zone is no longer recorded. |
|---|
| 323 | (11/2003, 1.64) |
|---|
| 324 | |
|---|
| 325 | <DT>Change "Use new name" for archived .EXP files |
|---|
| 326 | <DD>If you are reloading an archived .EXP file, you can copy it to be the |
|---|
| 327 | latest version of the current .EXP file, or supply a new name. Previously, |
|---|
| 328 | it saved the current file under a new name -- what was I thinking then? |
|---|
| 329 | (11/2003, 1.64) |
|---|
| 330 | |
|---|
| 331 | <DT>OS X compatible |
|---|
| 332 | <DD>This version of EXPGUI runs under Macintosh OS X(!) |
|---|
| 333 | (11/2003, 1.64) |
|---|
| 334 | |
|---|
| 335 | <DT>Add Multiple Histograms |
|---|
| 336 | <DD>This option allows two or more "banks" of data to be read in a single |
|---|
| 337 | pass for use with multibank diffractometers |
|---|
| 338 | (8/2003, 1.62) |
|---|
| 339 | |
|---|
| 340 | <P> |
|---|
| 341 | <DT>Instrument parameter file editor |
|---|
| 342 | <DD>This is used to modify and create instrument parameter files |
|---|
| 343 | (5/2003, 1.61) |
|---|
| 344 | |
|---|
| 345 | <DT>Absorption correction big fix. |
|---|
| 346 | <DD>The problem where a change made by EXPGUI causes EXPEDT to garble |
|---|
| 347 | the ABSCOR record has been located and fixed, finally. Thanks are due to |
|---|
| 348 | detailed bug reports from 3 different people, so that this bug could be |
|---|
| 349 | tracked down! |
|---|
| 350 | (5/2003, 1.61) |
|---|
| 351 | |
|---|
| 352 | |
|---|
| 353 | <DT>Change .gsas_config to c:\gsas.config on windows |
|---|
| 354 | <DD>The name ~/.gsas_config makes sense in UNIX but is clumsy in Windows |
|---|
| 355 | (5/2003, 1.61) |
|---|
| 356 | |
|---|
| 357 | <DT>LIVEPLOT export |
|---|
| 358 | <DD>Liveplot now exports data to FOX and .CSV files (to produce publication |
|---|
| 359 | quality graphics). |
|---|
| 360 | (4/2003, 1.60) |
|---|
| 361 | |
|---|
| 362 | <DT>Export to FOX |
|---|
| 363 | <DD>EXPGUI can now export coordinates & raw data to FOX |
|---|
| 364 | (Free Objects for Xtallography, objcryst.sourceforge.net) |
|---|
| 365 | via XML. |
|---|

|---|
| 370 | <DD>The "add histogram", EXCLEDT and BKGEDIT sections were reworked to |
|---|
| 371 | correct errors in handling TOF datasets. EXPGUI flags changes that |
|---|
| 372 | would require POWPREF to be run before GENLES and warns if POWPREF is not |

| 571 | <DD> |
|---|
| 572 | When an invalid entry is specified, (for example 1..0 is typed, instead |
|---|
| 573 | of 1.0) EXPGUI ignores the entry and (now) it is also displayed in red, to |
|---|
| 574 | flag the error. This only happens for entries on the main panes. For |
|---|
| 575 | entries on modal dialogs (where there a "done" or "keep" button), these |
|---|
| 576 | errors will be reported only when the button is pressed. (10/2000, 1.38) |

| 584 | "Non-shell" version of EXPGUI |
|---|
| 585 | <DD> |
|---|
| 586 | EXPGUI has two functions, 1) to act as a "shell" that calls the |
|---|
| 587 | various GSAS programs, and 2) to edit the .EXP file. For use with |
|---|
| 588 | MacGSAS (and possibly the standard Win-95 GSAS shell), it is possible |
|---|
| 589 | to turn off the "shell" features -- by calling EXPGUI with the argument |
|---|
| 590 | -noshell or /noshell or by setting environment variable EXPGUI_NOSHELL to 1. |
|---|
| 591 | This mode has not yet been tested and is not expected to |
|---|
| 592 | be needed due to the OS X release. (10/2000, 1.36) |

|---|
| 603 | <DD> |
|---|
| 604 | A mechanism where one can specify a new space group, cell, |
|---|
| 605 | and reinput all atoms for the phase (to get site syms correct). One can |
|---|
| 606 | keep the old atoms for the phase or replace them. It is possible |
|---|
| 607 | to do this manually or with a file import capability. |
|---|
| 608 | At present the only file type accepted is |
|---|
| 609 | the .CEL format from PowderCell. New format filters can be "dropped" in |
