I ran modelgenerator from the command line, like this:

    modelgenerator data.phy 4

The model choice is in the output file modelgenerator0.out.  The AIC1
(ie the AIC in its original form) selects the GTR+G model.  The AIC2
and BIC are slightly different, and take the size of the data into
account.  They recommend a slightly simpler model, the K81uf+G.
However, since I will be analysing these data with phyml on the web,
which does not implement that K81uf+G model, I will go with the GTR+G.

The data.phy_* files are usable as input files, eg for a
locally-installed phyml.
