[xingyu-alfred-liu]

Bug summary

Was playing with the example usage snippet in this page: https://foyer.mosdef.org/en/stable/topic_guides/usage_examples.html

Code to reproduce the behavior

# Paste your code here
import mbuild as mb
from mbuild.lib.molecules import Ethane

ethane_box = mb.fill_box(compound=Ethane(), n_compounds=100, box=[2, 2, 2])
ethane_box.save('ethane-box.gro')
ethane_box.save('ethane-box.top', forcefield_name='oplsaa')

• Which version of Foyer are you using? (python -c "import foyer; print(foyer.__version__)") 1.0.0
• Which version of Python (python --version)? python 3.11.11
• Which operating system? Ubuntu 22.04

# version check
>>> import foyer

>>> import mbuild
>>> mbuild.__version__
'1.0.0'

See my comment in the issue on mBuild as it relates to this as well. The documentation is lagging behind at the moment, which we're making a priority to update!
