[Biojava-l] Error training SimpleDistribution

[Oscar Lopes]

Hello!

I get this exception when I try to train a MarkovModel.
I have a few EmissionStates with SimpleDistribution and another few with 
UntrainableDistribution.
When I use UntrainableDistribution in all states, there is no problem.

Can anybody give me a hint??

Thanks in advance
