Check installation is not complete

[lczech]

Hi there,

in the Installation doc, it states that

python ipk.py --help

can be used to check the installation. My default python on Ubuntu 20.04.6 LTS is however Python 2.7.18, such that this fails. As ipk.py contains the python3, it might hence be better to use

./ipk.py --help

instead.

Then, the command succeeds. However, I did not make raxml-ng available to IPK yet, and hence when trying to run it, get the error

RuntimeError: RAxML-ng not found. Please check it exists in your PATH or provide a full filename

If the above command is meant to be a check for successful installation, I recommend checking there that raxml-ng is available to IPK :-)

Cheers
Lucas

The same is true when the ipk binary is not there. Apparently, it did not compile correctly the first time (not sure why - can't reproduce now), and despite the check above working, I then got

./ipk.py build -w ../test/ -r ../test/dataset.fasta -t ../test/dataset.newick -m GTR -a 0.42

This was fixed after repeating the download and compilation. But I think that when you state that ./ipk.py --help serves as a check of the installation, it should check that all binaries are there ;-)
