36<H3>C.1 File Menu</H3>
38The options on the File menu as is the custom contains the commands
39for reading and writing experiment files, as well as starting
40and ending the program.
43        Select an existing GSAS experiment to be used. If a name is entered
44        that does not exists, it is possible to create a new
45        experiment file from scratch.
46<DT>Save<DD>Saves modifications to the current experiment file to disk (shortcut Alt-S).
47<DT>Save As<DD>Saves modifications to the current experiment file to disk
48        under a new file name
49<DT>Reread .EXP file<DD>Reread the last saved version of the experiment file from disk.
50<DT>EraseHistory<DD>Deletes old history records to speed reading of the .EXP file.
51<DT>convert<DD>Convert a standard ASCII file to the direct access format used by GSAS (and for UNIX, the reverse)
52<DT>exit<DD>Exit EXPGUI (shortcut Alt-X or ^C)

58<h3>C.2 Options Menu</h3>
60This menu contains options that determine how EXPGUI runs.
[368]62<a name="archive"></a>
[225]63<DT>archive EXP<DD>Toggles archiving of .EXP files. When on, files are
[368]64        saved prior to each save or run of EXPEDT.
65        Each time a file is saved a note is placed in the .LST file
66        so that the saved file name can be associated with
67        the refinement stage.
69<B>UNIX:</B> Old .EXP files are saved in a compressed file named
70[expnam] where xxx = 000, 001..., if the the gzip
71program can be run by EXPGUI, or in an uncompressed file named
72[expnam] if gzip is not available.
[404]74Archived files can be loaded by using the File/Open (expnam) command:
75set the "Include Archived Files" checkbox, then select the file to be loaded.
76When an archived file is read, either the same experiment name can be used.
77In which case the archived file will replace the current version of the
78experiment file, or the archived file can be saved under a new name.
[368]80<B>Windows:</B> Old .EXP files are saved in a compressed form in
81a file named [expnam].ZIP, if program PKZIP.EXE is found in the
82same directory where EXPGUI is installed (typically c:\gsas\expgui).
83To read the archived files, you will
84need to use PKZIP or WINZIP to extract and rename them.
85If PKZIP is not installed, the files are archived by
86renaming them [expnam]!xxx.EXP. These archived files can be read
87directly by EXPGUI, but you are suggested to save them under
88a new name using the File/"Save As" option.
[225]90<DT>Use DISAGL Window<DD>When this option is set, results from DISAGL are
91         shown in a separate window. When it is not set, the results are
[368]92        written in the .LST file. Note that on Windows, LSTVIEW can interfere
93        with putting output into the DISAGL window. The solution is to
94        close LSTVIEW before running DISAGL.
96<a name="Autoupdate"></a>
97<DT>Autoload EXP<DD>Normally EXPGUI prompts before rereading the EXP
98file when GENLES, POWPREF,... or other GSAS programs run
99If this option is set, the new file is automatically read without a prompt.
100The advantage of leaving this option off, is that
101you can opt to not load the
102revised .EXP file, which means that you reject the last set of changes.
103This is useful if
104GENLES blows up or you have done something wrong. The advantage
105of turning "autoload EXP" on is
106that there is one less thing to do when running GSAS programs.
107Note that it is still possible to reverse changes, if
108<a href="#archive">archive mode</A> is on, but this may require more effort.
110<a name="Autoicon"></a>
111<DT>Iconify during GSAS<DD>
112If this option is turned on, the main EXPGUI window is shrunk to an icon
113(minimized) while GSAS programs are running and EXPGUI is suspended.
114The author prefers this mode, since there is no reason to have the
115screen cluttered with EXPGUI when it can't be used,
116but this is an option so that the mode can be turned off by those people
117who find this behavior annoying.
[225]119<a name="sortatoms"></a>
120<DT>Sort atoms by<DD>   Determines the order that atoms are displayed on the "Phase" pane
121        Atoms may be displayed sorted by number, atom type, site multiplity,
[257]122        occupancy, or by x, y or z coordinate
[301]124<IMG SRC="new.gif" HEIGHT=13 WIDTH=36 alt="New!">
[225]125Clicking on the heading above the atoms list cycles with the left
126mouse button cycles through the atom sort modes. Clicking with
127the right mouse button resets the atom sort mode to "number".
129<a name="sorthist"></a>
130<DT>Sort histograms by<DD>Determines the order that histograms are displayed on the
131        Histogram, Scaling and Profile panes
133        Histograms may be sorted by histogram number, histogram type,
134        original bank number, or diffraction angle/wavelength
135<DT><A href="expgui.html#multiplehistogram">Multiple hist. selection</A><DD>
136        When this mode is off, it is possible to modify parameters
137        and refinement flags for only a single histogram. For other settings,
138        it is possible to modify parameters and flags for groups of
139        histograms (see help for Mouse actions).
141        It does not make sense, however, to globally modify
142        instrument-related parameters and flags for different histogram types.
143        So global actions can be limited to a single class of histogram types
144        (e.g. TOF, CW Neutron,...), which allows these parameters to be set
145        for groups of similar histograms. Thus, if this mode is set to "All"
146        the Histogram and Profile panes are disabled.
147<DT>Override backspace<DD>This option is available in UNIX only, as there are different
148        ways that backspace can be implemented. When option is set
149        as "On," the backspace key is overridden to send a "delete"
150        character. If backspace does not work in a program such as
151        EXPEDT, change try the other setting for this option.
[315]153<a name="exptoolout"></a>
154<DT>Show EXPTOOL output<DD>
155Normally EXPGUI does not show the output from EXPTOOL, when
156actions like adding atoms, phases or histograms is performed.
157If there are problems, this option should be set to "on"
158so the error can be determined.
[225]160<DT>SaveOptions<DD>Save the current values for "Override backspace",
