Start likelihood:-Infinity after 50 initialisation attempts

[Omnipotent32]

Hi, I'm a fresh guy in using BDMM. I want to calculate the R0 of 5 large HIV-1 clusters identified by transmission network analysis, so I set the cluster serial number as demes. All I need to analyze are 5 cluster, then I set demes to 5. After finished other settings, I ran the BEAST, the I have the next warning. Could anyone tell me how to figure out this problem?

Oh the problem is done, I found I set the wrong sampling change time which not early than the height of the first sample

I'm having a similar problem. I'm trying to follow BDMM Beginner's Tutorial: https://github.com/denisekuehnert/bdmm/wiki/Beginner's-Tutorial with BEAST 2.6.7.

I think I followed BEAUti configuration there, but I get the same error as Omnipotent32:

P(birthDeathMigration.t:h3n2_2deme) = -Infinity (was -Infinity)

The first figure in Adjusting Priors section has "Sampling change time:" of 2.63, but the paragraph before that seems to indicate that this value should be 5.57. I tried 2.63 and 5.57, but they give the same error.

What am I doing wrong?

Thank you, Naoki
