2)Fateme S. Emami, Valeria Puddu, Rajiv J. Berry, Vikas Varshney, Siddharth V. Patwardhan, Carole C. Perry, and Hendrik Heinz.
"Correction to Force Field and a Surface Model Database for Silica to
Simulate Interfacial Properties in Atomic Resolution".
Chem. Mater.2016281406-407. http://dx.doi.org/10.1021/acs.chemmater.5b04760

2. Download interfaceff2gro from Github, follow the instructions in README.md to install conda and MDAnalysis, and you can get the top files if you do every step right.

1) Pls pay attention to the limitations in README.md!
