Dear Expert,
I came this problem while trying to generate ligand topology for use Gromacs.
I have gromacs 2018 and also amber installed in my system (CentOS7).
I installed acpype by extracting the .tar file and "python setup.py install".
I am following the tutorial give in this link:
https://code.google.com/archive/p/acpype/wikis/TutorialAcpype4Gromacs.wiki
The error report is shown below.
[main.localhost try1]$ acpype -i Ligand.pdb
