     177<h3>A.6 Constraints pane</h3>
     178<DL><DL>
     179GSAS offers two types of restraints that can be included in a model.
     180So called "soft constraints" or "restraints" penalize the fit if
     181aspects of a model (for example, bond lengths) differ from selected values.
     182So called "hard constraints" reduce the actual number of
     183parameters in a model,
     184by grouping parameters so that a single shift (possibly scaled) is
     185applied to each parameter in the group.
     186The constraints pane is used to set these "hard constraints."
     187At this time the only constraints that can be set in EXPGUI are on atomic
     188parameters (others can be set in EXPEDT).
     189<P>
     190Note that these constraints are only applied to shifts but not to the
     191actual values. This means that, for example,
     192if two atoms
     193are constrained so that the shift on their occupancy is the same, but
     194the initial occupancies differ, the in occupancy difference will not change
     195as the values refine.
     196<P>
     197<H4>Atom Constraints</H4>
     198The atom constraints editing pane appears below. Note that constraints can
     199be listed sorted by constraint number, phase number, lowest atom number or
     200variable by clicking on the buttons at the top of the pane.
     201<P>
     202To delete one or more constraints, click on the appropriate checkbuttons in the <B>Delete</B> column and the press the Delete button, below.
     203<img SRC="mc.gif" align=TEXTTOP>
     204Due to the way GSAS implements these constraints, a parameter can be included
     205in only one constraint. Should one or more parameters be constrained twice,
     206an error message is shown as shown below.
     207Note that the constraint number is displayed as red, for constraints that
     208have conflicts in the constraints editing pane (see above.)
     209<img SRC="mcerr.gif" align=TEXTTOP>
     210<P>
     211<img SRC="mcedit.gif" align=LEFT>
     212<img SRC="mcvar.gif" align=RIGHT>
     213When the edit button for a constraint is pressed, the constraint is
     214opened for editing. Controls are available to select the phase, variable,
     215multiplier and atom(s). Note that for atom selection, use of the control key
     216and the left mouse button allow individual atoms to be selected or deselected.
     217Shift and the left mouse button allow ranges of atoms to be selected and the
     218right mouse button selects all atoms
     219<A href="#mouseactions">(see Mouse Actions)</A>.
     220<P>
     221Note that it is inappropriate
     222to constrain different types of parameters together, for example X and Uiso.
     223The left-most variable button is the "master" which
     224determines what variable are allowed in the
     225other variable buttons.
     226<P>
     227When the "New Constraint" button is pressed, a blank constraint editing
     228window is opened. Note that any variable to the right may then be selected,
     229including two special codes, Uxx and XYZU. XYZU creates four constraints,
     230requiring the shifts on x, y, z and Uiso to be the same for all the selected
     231atoms. Uxx does the same for the six anisotropic displacement parameters.
     232These special codes are valuable for atoms that share a site.
     233<P>
     234Note that only 100 parameters may be included in a constraint,
     235with one exception. When shifts for Uiso for all atoms in a phase
     236are constrained, this counts as a single parameter. If more than 100
     237parameters are entered for a constraint, an error message is shown.
     238Up to 2000 atomic constraints may be entered.
     239EXPGUI does not warn if you exceed this limit.

     242<P>
     243<h3>A.7 Preferential Orientation Pane</h3></a>
     244The Preferential Orientation Pane is used to control parameters related
     245to fitting parameters using the March-Dollase formulation
     246for preferred orientation. In this model one or more axes are designated
     247as directions [designated by (<i>hkl</i>)] where crystallites are over
     248(Ratio > 1) or underrepresented (Ratio < 1).
     249The checkbox to the right of the Ratio value determines if it will
     250be refined.
     251<img SRC="po1.gif" align=TEXTTOP>
     252If more than one axis is present, one must define the relative fraction
     253of preferred orientation for each direction. These fractions are normalized,
     254so do not vary the fractions for all directions in a phase.
     255<img SRC="po2.gif" align=TEXTTOP>
     256If
     257<A href="#multiplehistogram">
     258"Multiple Histogram Selection" mode</A> is set to any value other than
     259"Off", all terms are displayed for all selected histograms.
     260No attempt is made to group terms or flags.
     261<P>
     262Note that the other model for treating preferred orientation -- the orientation
     263distribution function (spherical harmonics) is not yet implemented
     264in EXPGUI and must be accessed from EXPEDT.

     269<h3>B.1 Multiple Histogram Selection</h3></a>
     270<DL><DL>
     271This mode allows parameters to be changed for groups of
     272histograms.
     273When the "Multiple Histogram Selection" mode is off,
     274it is possible to modify parameters
     275and refinement flags for only a single histogram, but
     276the other settings allow groups of histograms
     277to be selected and modified.
     278<A href="#mouseactions">(see Mouse Actions)</A>.
     279
     280It does not make sense, however, to globally modify
     281instrument-related parameters and flags for different
     282histogram types.
     283So global actions can be limited to a single class
     284of histogram types (e.g. TOF, CW Neutron,...), which
     285allows these parameters to be set for groups of
     286similar histograms. Thus, if this mode is set to "All"
     287the Histogram and Profile panes are disabled.
     288<P>
     289The setting for "Multiple Histogram Selection" mode is
     290selected using the "Multiple Hist. Selection" item on the
     291Options menu to create a submenu. Also on this submenu is an option
     292"Group Phases Together" that controls how EXPGUI treats phases having
     293the same profile type when multiple histograms are selected. If
     294the "Group Phases Together" option is on, then the refinement flags for
     295all phases with the same histogram types are grouped together, when possible.
     296If this option is off, phases are treated separately.

     304possible to select a range by using the Shift key with the left mouse
     305button. To select or deselect individual entries, use the Control key

    187 <DL><DL>
    188 GSAS offers two types of restraints that can be included in a model.
    189 So called "soft constraints" or "restraints" penalize the fit if
    190 aspects of a model (for example, bond lengths) differ from selected values.
    191 So called "hard constraints" reduce the actual number of
    192 parameters in a model,
    193 by grouping parameters so that a single shift (possibly scaled) is
    194 applied to each parameter in the group.
    195 The constraints panel is used to set these "hard constraints."
    196 At this time the only constraints that can be set in EXPGUI are on atomic
    197 parameters (others can be set in EXPEDT).
    198 <P>
    199 Note that these constraints are only applied to shifts, so that if two atoms
    200 are constrained so that the shift on their occupancy is the same, but
    201 the initial occupancies differ, the difference will be maintained as the
    202 values refine.

    204 <H4>Atom Constraints</H3>
    205 The atom constraints editing page appears below. Note that constraints can
    206 be listed sorted by constraint number, phase number, lowest atom number or
    207 variable by clicking on the buttons at the top of the page.
    208 <P>
    209 To delete one or more constraints, click on the appropriate checkbuttons in the <B>Delete</B> column and the press the Delete button, below.
    210 <img SRC="mc.gif" align=TEXTTOP>
    211 Due to the way GSAS implements these constraints, a parameter can be included
    212 in only one constraint. Should one or more parameters be constrained twice,
    213 an error message is shown as shown below.
    214 Note that the constraint number is displayed as red, for constraints that
    215 have conflicts in the constraints editing page (see above.)

    220 When the edit button for a constraint is pressed, the constraint is
    221 opened for editing. Controls are available to select the phase, variable,
    222 multiplier and atom(s). Note that for atom selection, use of the control key
    223 and the left mouse button allow individual atoms to be selected or deselected.
    224 Shift and the left mouse button allow ranges of atoms to be selected and the
    225 right mouse button selects all atoms
    226 <A href="#mouseactions">(see Mouse Actions)</A>.
    227 <P>
    228 Note that it is inappropriate
    229 to constrain different types of parameters together, for example X and Uiso.
    230 The left-most variable button is the "master" which
    231 determines what variable are allowed in the
    232 other variable buttons.
    233 <P>
    234 When the "New Constraint" button is pressed, a blank constraint editing
    235 window is opened. Note that any variable to the right may then be selected,
    236 including two special codes, Uxx and XYZU. XYZU creates four constraints,
    237 requiring the shifts on x, y, z and Uiso to be the same for all the selected
    238 atoms. Uxx does the same for the six anisotropic displacement parameters.
    239 These special codes are valuable for atoms that share a site.
    240 <P>
    241 Note that only 100 parameters may be included in a constraint,
    242 with one exception. When shifts for Uiso for all atoms in a phase
    243 are constrained, this counts as a single parameter. If more than 100
    244 parameters are entered for a constraint, an error message is shown.
    245 Up to 2000 atomic constraints may be entered.
    246 EXPGUI does not warn if you exceed this limit.

    250 <h2>7. Multiple Histogram Selection</h2></a>
    251 <DL><DL>
    252 This mode allows parameters to be changed for groups of
    253 histograms.
    254 When the "Multiple Histogram Selection" mode is off,
    255 it is possible to modify parameters
    256 and refinement flags for only a single histogram, but
    257 the other settings allow groups of histograms
    258 to be selected and modified.
    259 <A href="#mouseactions">(see Mouse Actions)</A>.
    260 
    261 It does not make sense, however, to globally modify
    262 instrument-related parameters and flags for different
    263 histogram types.
    264 So global actions can be limited to a single class
    265 of histogram types (e.g. TOF, CW Neutron,...), which
    266 allows these parameters to be set for groups of
    267 similar histograms. Thus, if this mode is set to "All"
    268 the Histogram and Profile panels are disabled.
    269 <P>
    270 The setting for "Multiple Histogram Selection" mode is
    271 selected using the "Multiple Hist. Selection" item on the
    272 Options menu to create a submenu. Also on this submenu is an option
    273 "Group Phases Together" that controls how EXPGUI treats phases having
    274 the same profile type when multiple histograms are selected. If
    275 the "Group Phases Together" option is on, then the refinement flags for
    276 all phases with the same histogram types are grouped together, when possible.
    277 If this option is off, phases are treated separately.

    285 possible to select a range by using the Shift key with the left mouse
    286 button. To select or deselect individual entries, use the Control key
