QUIRK NOTE FOR PARTITIONED ALIGNMENTS:

If you have a RAXML-type .txt file specifying where partitions begin and end want to build a tree, you have to let iqtree determine those partitions for you and use the resultant XXXbest_scheme.nex file as input for "real" tree building. It doesn't correctly recognize models in RAXML-type partition files for treebuilding.

ex. start with something like:

iqtree2 -s sequences.phy -p raxml_type_partitionsfile.txt -ntmax 10 -T AUTO -m TESTMERGEONLY

followed by:

iqtree2 -s sequences.phy -p raxml_type_partitionsfile.txt.best_scheme.nex ...
