Dear Fabricia,

Dear Fabricia,
Thank you for using AliSim. Can you try with:

iqtree2 --alisim alignment_codon -m "MG2K{1.0,0.3,0.5}" -t tree.nwk

(with "" covers the model and its parameters).

Cheers,
Nhan

Hello,

I am trying to simulate some sequence alignment using a codon model.
I have tried the following command:

iqtree2 --alisim alignment_codon -m MG2K{1.0,0.3,0.5} -t tree.nwk
tree.nwk is the same tree as the example in here
http://www.iqtree.org/doc/AliSim

I get the following error message:

Do you know why this is happens?
I use a Mac OS Sonoma M2 chip.

Thanks,
