It does not work with Chimera 1.12

[lvelasco022]

I tried to run gpathfinder using the Chimera version 1.12, that it was the one I had previously installed, and the following error appeared:

Traceback (most recent call last):

I recommend using the latest version of Chimera, since using a more recent version of Chimera (1.13 or 1.14) is enough to overcome the error.
