After a user and their current initialisation file are
chosen, it is possible to choose/change the Data base where all measurement and
result (spectra) files will be gathered. The Material>>Sample combo box
contains the list of the materials and samples already defined in the chosen
Data base. It is possible to add to or edit this list by pressing the Add/Edit
button. This combo box displays the list of the samples from the main root of
the base and the first branch of the hierarchically organised structure. The
roots are the materials used for the studies. The first branches are the samples
produced from these materials. The combo box displays these two items as a
“material >> sample” structure. The currently used
“material>>structure” pair is saved in the configuration file and this
pair is chosen when this file is loaded. See the help file on the Experiment Data Base program for more details.
