BEAST Classic, discrete mugration: java.lang.Error: randomChoiceUnnormalized falls through -- negative components in input distribution?
Pavel Rinkman
Hello, everyone
Please, I am asking for help from all those who have successfully used discrete phylogeography with BEAST Classic! 🙏
I am trying to run the discrete mugration model with BEAST Classic package following the tutorial. I did the model construction in BEAUTi word-by-word but got strange results. Actually, the results, trees & logs turned out normal, according to the tutorial. However, I caught the following in stderr:
Warning: removing transform class beast.base.inference.operator.kernel.Transform$LogConstrainedSumTransform because it should have at least 2 dimensions, but it has 0 Turning on scaling to prevent numeric instability 1.0201 … 0 NaN 1 NaN 2 NaN 3 NaN 4 NaN java.lang.Error: randomChoiceUnnormalized falls through -- negative components in input distribution? Please report error to MarcYou may find all files here
I see such the first time and do not understand the reason. Moreover, I have compared my XML with the example from the package GitHub repository and did not detect the difference, of course, besides new BEAST 2.7 default operators. I tried to run the example, but it falls with:
Error 1017 parsing the xml input file Class could not be found. Did you mean beast.base.inference.MCMC? Perhaps a package required for this class is not installed? Error detected about here: <beast> <run id='mcmc' spec='MCMC'>May this error influence the results of real analyses? How to correct my XMLs to eradicate it? I feel that I am silly due to the fact that I could not successfully run a simple guide and do not understand the nature of these errors.
Best regards,
Pavel
