The software may be used for estimating proportions other than coverage proportions but users should be aware that the application has some limitations:

The shape parameters for the prior are restricted to range between 1 and 35

The size of the denominator for the likelihood is restricted to range between 1 and 256

These limitations may be changed in the TCL source.

Some users with Windows 7 and later have reported problems saving the diagnostic plot. This can be fixed by running the program in compatibility mode for Windows XP (Service Pack 2). To do this:

  1. Close BayesSQUEAC (if it is open).

  2. Right click on BayesSQUEAC icon and click "Properties".

  3. Select the "Compatibility" tab.

  4. Check "Run this program in compatibility mode for:".

  5. Specify "Windows XP (Service Pack 2)".

  6. Click the "OK" button.

All should now work.
