Hi,

I have tried BEAST for calculating the evolutionary divergence time for my study, consisting of ~ 80 taxa & having a length of ~80,000 bps per taxa.

After the run was completed, the BEAST gave the output which I couldn't interpret. In the acceptance rate column, for various operators, it gave the suggestion to: Set the scale factor to some values..

How to set the scale factor? Also the posterior ESS & likelihood values became infinity after a few thousand sample runs.

In the tracer output also, the ESS values are all very small. Also, the mean, stdev, variance and all other values are also not shown properly.

I need to calculate the divergence time of a particular gene and am struck with this. Any advice on this would be highly helpful.
