ERROR: phylotree.cpp:4072 XXX failed

[quliping]

Hello, I tried to build a phylogenetic tree with 1159 genomes, but I got some errors. I have no idea what happed. Here is my command:
iqtree2 --mem 200G -m MFP -s genomes_Phylogeny/AOA.ar53.user_msa.fasta -t genomes_Phylogeny/AOA.ar53.user_msa.fasttree -T 56 -B 1000 -o Bathyarchaeia_Ref_GCA_003096235.1,Bathyarchaeia_Ref_GCA_029762755.1 --keep-ident. I tried to set '--mem' to higher RAM value and tried to run command without this option, but it didn't work.

Here is the log file: AOA.ar53.user_msa.fasta.log.txt

Here is abstract of the error:

The problem is that your input tree genomes_Phylogeny/AOA.ar53.user_msa.fasttree is a multifurcating tree. The tree search doesn't work with multifurcating starting tree. You need to convert it to bifurcating tree.
