Custom mixture profiles #66

Hi Minh,

I am trying to run IQ-TREE with custom mixture profiles (maybe see also #65). The command line is

iqtree -nt 4 -s A00000.1y77.ALL_GB.NoIdt -mdef clusters_08_lclr_iqtree.nex -m "GTR20+CF08Model+G" -redo -mwopt

However, the frequency mixture weights are not estimated (but set to 1/8 in this case). Also, the frequency mixtures are not the ones specified in the model file, but are the empirical ones. Effectively, this is running a model with eight equal, empirical frequency profiles.

Maybe I am not correctly specifying the frequency mixture model?

Thanks,
Dominik
