272. Add a phase and atoms to the Experiment

31The next step is to define a phase. (Note that
32in EXPEDT, one must define a phase before reading in
33histograms but in EXPGUI, this can be done in either order.)
34Switch to the Phase pane, and press the "Add Phase" button.

37<BR>Enter the appropriate information in the
38add new phase window and press the "Add" button.

41Since a common source of errors is to improperly format
42the space group for GSAS, the generated operators are shown
43in a window.
44These should be checked.

48Since the operators above are correct,
49press the Continue button and the
50phase is added and the output created from adding the
51phase is shown in a window. Press OK to continue.
52Press the "1" button that has just been added to
53the Phase pane to display the phase you have just entered.

58Now we will add the atoms to the phase
59by pressing the "Add New Atom" button
60in the lower left of the Phase pane.
61<BR clear=left>
62<img src="addatom1.gif" align=left>
63At first the add atom menu appears with room for a
64single atom to be added. Press the "More atoms" button 5 times to create
65spaces for six atoms and add the atom information found on page 66.
66<BR clear=left>
67<P><img src="addatom2.gif" align=left>
68After all atoms have been typed in, press the "Add Atoms" button and then
69the screen below appears, so that it can be verified that the atoms
70have been added correctly.
71<BR clear=left>

74After pressing OK. The contents of the phase is displayed as is shown below.
