When you start the program you will see this GUI:

The tabs for calculations are not available until you load EoS.
In the settings tab you can:
- Set the Temperature scale for calculations (K or C).
- Set the display mode: 'Expert' mode shows more intermediate results of calculations, and the results from the different elastic relaxation models, when relevant.
- Set a log file. The log file will keep a record of everything that you do with the program, and it sometimes contains more output than is displayed in the output window of the program. It is a text file that can be edited with Notepad or similar text editors.
The programs tab gives you direct access to other programs in the EosFit7 program suite, if you have installed them.
The info tab has basic program information (version and date) and references to papers that describe the theory of host-inclusion elasticity and the methods of calculation used in the program.
