coercing to Unicode: need string or buffer, PosixPath found

Hi,
when trying to set settings in jupyter notebook:
settings = Settings(fn_yaff='pars_cov.txt', plot_traj='All', xyz_traj=True)
The following error occurred:

---

TypeError Traceback (most recent call last)
in ()
----> 1 settings = Settings(fn_yaff='pars_cov.txt', plot_traj='All', xyz_traj=True)

/Users/ignaspakamore/Anaconda/anaconda2/lib/python2.7/site-packages/quickff/settings.py in init(self, fn, **kwargs)

Dear ignaspakamore,

first of all, thank you for reporting this and sorry for the late reply. This might have to do with compatibility between python 3 and python 2. If this still is an issue, maybe the following small hack in the source code of QuickFF could work.

In the line 168 of settings.py mentioned in the second paragraph of your traceback, change the line
self.read_config_file(fn_default)

to the line
self.read_config_file(str(fn_default))

and reinstall QuickFF.

cheers,
Louis
