problems with maximum likelihood analysis in POY 5.1.1

[Lourdes Echevarria]

Hello,

I am running a small analysis to test the performance of POY when running likelihood analysis.

I am submitting the following commands (in a parallel environment of 40 processors):

read(prealigned:("16S.fas",tcm:(1,1)))

search(max_time:00:00:30)

select()

transform(likelihood:(gtr,rates:gamma:(4),priors:estimate))

search(max_time:00:04:00)

report("arbol.tre", trees:(branches), "reporte.txt", lkmodel)

exit()

The first search runs normally, but right after it finishes de Wagner trees, the following error messages appear:

poy: likelihood.c:2544: readjust_brents_gtr: Assertion `b >= x' failed.

I would really appreciate help to understand what is happening, where the error is.

Thanks in advance
