You can switch between these two options by clicking "back" on your web browser, change the choice, then click "show the datafile" again.
• When you are finished, click the "File->Save As" on your web browser, type in the name of the file to be saved.
• You are done!

• For binary factor locus type, we restrict the number of binary factors to be equal to the number of alleles.
• You can input multiple "lines" in one window, but "lines" are separated by semicolons. For example, if you select two liability classes and there are three penetrances in each liability class, you can enter something like this:

 		0.0 1.0 1.0; 0.0 0.5 0.9

• Bugs!!!
• Whether the online instruction is clear enough.
• Whether the online instruction is too trivial/distracting and should be moved to separated pages
• Any suggestions on improving the program.

Happy testing!
