272. Add a phase 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.
35Enter the appropriate information in the
36"add new phase" window and press the Add button.

40Since a common source of errors is to improperly format
41the space group for GSAS, the generated operators are shown
42in a window.
43These should be checked.
44If you press Redo, you are given a chance to correct
45the space group.

49Since the operators above are correct,
50press the Continue button and the
51phase is added and the output created from adding the
52phase is shown in a window. Press OK to continue.
53Press the "1" button that has just been added to
54the Phase pane to display the phase you have just entered.

59While we could add atoms to the phase now, this will be done later to
60keep in sync with the GSAS tutorial.
