Sorry for answering my own mail. When trying the examples of graphlan I
noticed that some files are missing:
graphlan/examples/guide $ ./step3.sh
Error: No tree file found: guide_2.xml
Error: No tree file found: guide_3.xml
Error: No tree file found: guide_3.xml
graphlan/examples/guide $ ./step4.sh
Error: No tree file found: guide_3.xml
Error: No tree file found: guide_4.xml
Error: No tree file found: guide_4.xml
I'm not sure about this, please check:
graphlan/examples/internal_labels $ ./step4.sh
Classes not implemented for external annotations
Classes not implemented for external annotations
...
I also observed two times warnings from matplotlib saying:
/usr/lib/python2.7/dist-packages/matplotlib/projections/polar.py:149: RuntimeWarning: invalid value encountered in true_divide
A real error occures with
graphlan/examples/phylo_small $ ./run.sh
Traceback (most recent call last):

BTW, a conversion to Python 3 for graphlan as well as pyphlan would be
nice.
Kind regards
Andreas.
