this looks very similar to the issue recently reported on the raxml google group here:
https://groups.google.com/forum/#!topic/raxml/gluJCb9PGvA
Could you please try to reproduce with the latest dev and/or --force model_lh_impr
as suggested in the above thread?
Thanks for the suggestion.
I've tried the following:
--force model_lh_impr
--force model_lh_impr --precision 12 --blmin 0.000000001
However, the issue persists in all of these cases.
Just an update, the issue seems to be limited to the +ASC_STAM
model parameter. The same input with either +ASC_LEWIS
or no ascertainment bias correction has no issue.
Thanks for checking!
Can I get your alignment to reproduce the error?
Sure, here is a trimmed down version of the original that gives the same error: https://drive.google.com/open?id=1_QWid_PSvbkkDucibHVVOHbmDdcjBNhd
thanks, I'll have a look!
just a side note: if you do have the full MSA, it is preferable to use it instead of +ASC_STAM
model.
I wasn't aware of that. Can you briefly outline what the advantage of using the full MSA is over using ascertainment bias correction? Would a similar result be achieved by including variant sites as trinucleotides instead? Thanks you.
The main shortcoming of ascertainment bias correction is that it ignores the missing data/indels in the original MSA. Please see detailed discussion here: https://academic.oup.com/sysbio/article/64/6/1032/1669226 Thus, I think that using trinucleotides won't help much.
Issue description: raxml-ng fails on certain input for an unknown reason. The time until failure seems to depend on the random seed used. Jobs have been run on an HPC with 8 cpus and 32 GB ram requested.
