chimera not found

[paiardin]

Hi,
I've successfully installed gpathfinder on Mac OS 10.13, and latest Chimera 1.16.

When I run the command:

(gpathfinder) MacBook-Pro-di-Alessandro-4:Downloads paiardin$ gpath run input.yaml

I get this error:

GPathFinder: Identification of ligand pathways by a
multi-objective genetic algorithm
2019, InsiliChem · v1.2.0

Traceback (most recent call last):

OSError: [Errno 2] No such file or directory

It seems that is a path in pychimera/core.py that cannot be found.

Thanks for your help!
