error: wrong likelihood derivatives #33

Closed vmaffei closed 7 years ago

vmaffei commented 7 years ago

Hello! I am trying to create a tree using raxml-ng on an alignment (99322 taxa and 1285 sites) using 

./raxml-ng --msa alignment_pfiltered.fasta --model GTR+G4 --search --threads 45 --tree rand{20}

Unfortunately, I run into the following error: 

terminate called after throwing an instance of 'std::runtime_error'
  what():  ERROR in branch lenght optimization: wrong likelihood derivatives

Any guidance on what I'm missing or how I might troubleshoot?

Please try adding --rate-scalers on and reduce the number of threads to 8-16.

If it doesn't help, could you please send me your alignment and raxml log file, such that I can reproduce the error?

Ah great. --rate-scalers on did the trick. Thank you for your help and great software!
