IQtree crash "Too many iterations in tqli"

[renee....@gmail.com]

Hi all,

I've just downloaded and installed IQtree on my new computer, so this could be my fault. However, I've run IQtree before without any issues.

I'm running the current version of IQtree-OMP, and running a multi-gene partitioned analysis with a 1000 replicate non-parametric bootstrap:

iqtree-omp -s concat_alignment_m2.phy -sp partitionandmodels.nex -b 1000 -nt 4

It keeps crashing at different points in the analysis with this error:

It got through 29 replicates before it crashed this time, not sure why it worked to that point. Is this an out of memory error?

Sorry, google groups is not doing anything when I click "Attach a file", otherwise would have attached the log.

Thanks

In addition, I have 32 GB of RAM, so putting the 4 processors onto it means I am giving it a massive amount of memory on what is not a huge dataset (56 individuals/5 partitions/~2000 bp.

Dear Renee,

which platform (Windows, Mac, or Linux) that you ran IQ-TREE?

can you please send me per personal email the log file and the input files? I will have a more careful look

Thanks, Minh
