Hello anyone

I'm trying to perform an analysis of BSSVS (a Bayesian Stochastic Search Variable Selection), but when I run BEAST (including Version 1.75, 1.8.0, 1.8.1 and 1.8.2) under Windows 7(64bit),  using BEAGLE 2.1, the program displays the error message:

"Underflow calculating likelihood. Attempting a rescaling...

Underflow calculating likelihood. Attempting a rescaling...

State 1000467: State was not correctly restored after reject step.

Likelihood before: -9781.963977882762 Likelihood after: -9022.104627201184

Operator: bitFlip(Locations.indicators) bitFlip(Locations.indicators)"

Alternatively, I tried to run it under iMAC (yosemite) ,but it can work only for 1 millions generations. And after that the same problems stilly occured.

Does anyone know how I can solve this problem?

The details of the BEAGLE  as follows.

Thanks.

Best regards,

Raindy
