593. Add data (histogram) to the Experiment
60</H1>
61
62The next step in the tutorial is to add data. Note that
63GSAS uses the term
64histogram to refer to a powder diffraction data set.
65To add data, switch to the Histogram in EXPGUI pane and press the
66"Add New Histogram" button in the lower right.
67<img src="addhs1.gif" ALIGN=LEFT>
68This brings up the "add new histogram" dialog, to the left.
69Press on the upper "Select File" button for a dialog box to select
70a data file.
71
72<BR clear=left>
73<P><img src="addhs2a.gif" ALIGN=LEFT>
74Select the appropriate file, in this case garnet.raw and press
75the "Open" button.
76
77At this stage, different things can happen.
78If the file is not correctly formatted,
79<A HREF="../tutorial1/nickelnotes.html#reformat">a dialog will offer
80to convert the file to the correct format.</a>
81Also, in some cases, the data file specifies the name of the instrument
82parameter file. If so, that name will be loaded into the "Instrument
83Parameter file" box. If not, as in this case, the file must be selected
84by pressing the lower "Select File" button which creates a
85dialog box to select an instrument parameter file, similar
86to the one above.
87<BR clear=left>
88<P><img src="addhs3a.gif" ALIGN=LEFT>
89The appropriate instrument parameter file is then located and selected.
90Note that since only one bank of data is present in the file,
91bank 1 is selected automatically however one must know something
92about the instrument parameter file to know that bank 1 is the
93appropriate contents.
94Finally one must enter either the minimum d-space or
95maximum two-theta to be used from the data (note that
96this value can be changed later if need be from EXPEDT). A
97good way to do this is to use
98<A HREF="../tutorial1/nickelnotes.html#rawplot">RAWPLOT</A>
99to look at the data. This is done
100by pressing the "Run RAWPLOT" button at the
101lower right <A HREF="../tutorial1/nickelnotes.html#rawplot">(example).</A>
102The GSAS tutorial in the manual suggests using 159 for this refinement.
103
104When all input is complete, press Add to run program EXPTOOL and read the
105data into the .EXP file.
106
107<BR clear=left>
108<P><img src="addhs4a.gif" ALIGN=LEFT>
109The results from the EXPTOOL are shown in a separate box, so
110that errors can be noted. After OK is pressed, the histogram
111is now listed on the Histogram pane (see below).
