EXPGUI, Menu Contents
C. Menu Contents
Note that the figures on this page are likely to be out of date with
respect to the text. The text is updated more frequently. Also, note
that not all menu options are available in Windows.
C.1 File Menu
The options on the File menu as is the custom contains the commands
for reading and writing experiment files, as well as starting
and ending the program.
- Open
-
Select an existing GSAS experiment to be used. If a name is entered
that does not exists, it is possible to create a new
experiment file from scratch.
- expnam
-
Equivalent to Open, included since this is the command used in other
GSAS shells to select GSAS experiments.
- Save
- Saves modifications to the current experiment file to disk (shortcut Alt-S).
- Save As
- Saves modifications to the current experiment file to disk
under a new file name
- Reread .EXP file
- Reread the last saved version of the experiment file from disk.
- EraseHistory
- Deletes old history records to speed reading of the .EXP file.
- convert
- Convert a standard ASCII file to the direct access format used by GSAS (and for UNIX, the reverse)
- exit
- Exit EXPGUI (shortcut Alt-X or ^C)
C.2 Options Menu
This menu contains options that determine how EXPGUI runs.
- archive EXP
- Toggles archiving of .EXP files. When on, files are
saved before they are overwritten by EXPGUI as a file
named EXPNAM.Oxx where xx is a pair of hexidecimal
digits (01, 02,..., 09, 0A,... OF, 10,... FF).
Each time that EXPGUI archives a file, note is placed in the .LST file
so that the saved file name can be associated with
the refinement stage. Turning this option off, prevents EXPGUI
from creating these EXPNAM.Oxx archive files, but
the will still be created by EXPEDT, GENLES,...
- Use DISAGL Window
- When this option is set, results from DISAGL are
shown in a separate window. When it is not set, the results are
written in the .LST file. Note that on Windows, LSTVIEW can interfere
with putting output into the DISAGL window. The solution is to
close LSTVIEW before running DISAGL.
- Autoload EXP
- Normally EXPGUI prompts before rereading the EXP
file when GENLES, POWPREF,... or other GSAS programs run
If this option is set, the new file is automatically read without a prompt.
The advantage of leaving this option off, is that
you can opt to not load the
revised .EXP file, which means that you reject the last set of changes.
This is useful if
GENLES blows up or you have done something wrong. The advantage
of turning "autoload EXP" on is
that there is one less thing to do when running GSAS programs.
Note that it is still possible to reverse changes, if
archive files, but this may require more effort.
- Iconify during GSAS
-
If this option is turned on, the main EXPGUI window is shrunk to an icon
(minimized) while GSAS programs are running and EXPGUI is suspended.
The author prefers this mode, since there is no reason to have the
screen cluttered with EXPGUI when it can't be used,
but this is an option so that the mode can be turned off by those people
who find this behavior annoying.
- Autostart GRWND
-
This option is available on Windows-95, -98 and -ME to deal with a operating
system quirk that prevents the starting of the GRWND.EXE program,
needed for graphics in GSAS programs such as POWPLOT, RAWPLOT, EXPEDT,...
(this program is not needed for EXPGUI graphics, such as LIVEPLOT). It
is not understood why this error happens or how to prevent it. One cure
is to start this GRWND.EXE program before starting the GSAS program.
If this option is selected, each time a GSAS program is started, a separate
program TLIST.EXE is used to check if GRWND.EXE is running. If it is not,
EXPGUI will start this program before starting the requested GSAS program.
- Sort atoms by
- Determines the order that atoms are displayed on the "Phase" pane
Atoms may be displayed sorted by number, atom type, site multiplity,
occupancy, or by x, y or z coordinate
Clicking on the heading above the atoms list cycles with the left
mouse button cycles through the atom sort modes. Clicking with
the right mouse button resets the atom sort mode to "number".
- Sort histograms by
- Determines the order that histograms are displayed on the
Histogram, Scaling and Profile panes
Histograms may be sorted by histogram number, histogram type,
original bank number, or diffraction angle/wavelength
- Multiple hist. selection
-
When this mode is off, it is possible to modify parameters
and refinement flags for only a single histogram. For other settings,
it is possible to modify parameters and flags for groups of
histograms (see help for Mouse actions).
It does not make sense, however, to globally modify
instrument-related parameters and flags for different histogram types.
So global actions can be limited to a single class of histogram types
(e.g. TOF, CW Neutron,...), which allows these parameters to be set
for groups of similar histograms. Thus, if this mode is set to "All"
the Histogram and Profile panes are disabled.
- Override backspace
- This option is available in UNIX only, as there are different
ways that backspace can be implemented. When option is set
as "On," the backspace key is overridden to send a "delete"
character. If backspace does not work in a program such as
EXPEDT, change try the other setting for this option.
- Set Screen Font
-
This menu changes the fonts used in most sections of EXPGUI.
Note that this setting can be saved with the
SaveOptions menu option (below) so that EXPGUI automatically
starts with the chosen font.
- Show EXPTOOL output
-
Normally EXPGUI does not show the output from EXPTOOL, when
actions like adding atoms, phases or histograms is performed.
If an error is detected, the output is shown. If
there are problems with adding phases, atoms, histograms... and
a window showing an error does not appear,
this option should be set to "on" so the output from EXPTOOL is
always shown.
- SaveOptions
- Save the current values for "Override backspace",
"Sort atoms by",
"Sort histograms by",
"archive EXP",
"Autoload EXP",
"Set Screen Font",
and
"Iconify during GSAS"
