Frequently Asked Questions
How can I join the Open Force Field Consortium as an Industry Partner?
See the Open Force Field Consortium page for more information on how to join.
How can I join the Open Force Field Consortium as an Academic Investigator?
Get in touch with one of the current Open Force Field Investigators if you’re interested in joining as an investigator.
How can I stay up to date with Open Force Field Initiative activites and developments?
You can sign up for our mailing list here.
What is the scope of your current funding?
The Open Force Field Consortium is an industry-funded effort to develop small molecule force fields, and we are seeking other sources of funding (federal, philanthropic) to broaden this effort in collaboration with other scientists.
Do you have plans to broaden your effort to include protein and biopolymer force fields?
We would like to partner with the biopolymer force field community to build a family of fully consistent general biopolymer and small molecule force fields, with the goal of fully consistent handling of biopolymers and small molecules, including natural (proteins, RNA, DNA) and unnatural (e.g. peptoids) biopolymers, as well as posttranslational modifications and nonnatural amino acids. Handling of unusual nonnatural amino acids or bases can be a major headache with current force fields, but our approach will allow a single simple force field to consistently treat biopolymers and small molecules. This expanded effort is not within the current scope of Consortium funding, and would benefit from bringing in partners with significant expertise in biopolymer force field development.
Will your effort compete with other force field projects?
Our initiative focuses on building software, infrastructure, and force fields to benefit the entire molecular simulation community by broadly enabling force field science. Our view is that this field requires the participation of a wide variety of talented researchers. Collaborations like ours are needed in order to update aging force field software infrastructure, a much larger task than a single group could accomplish. We hope to partner with other force field projects to ensure the infrastructure we are building will be broadly useful to all major force field development efforts.
We firmly believe that research in this space is not a zero-sum game; with the rising interest in physical methods to help guide pharmaceutical discovery, there is a need for new and better force fields and infrastructure, and this need can drive the availability of additional funds. Moreover, our current efforts focus on small molecule force field development, and we are not currently engaged directly in biomolecular (i.e. protein, lipid, carbohydrate) force field development.
Can we use your software in our force field effort?
Yes! Everything is open source under permissive licenses (generally the MIT License). We are also open to suggestions from the community, as well as community input on the codes and research directions. Please contribute to our GitHub issue trackers for projects at http://github.com/openforcefield, or even feel free to contribute code if you find it useful!
How can we collaborate with you?
Collaborations can be science-focused or software-focused; if you are willing to commit to open science and open source software, you’re welcome to get involved with one of our science sub-groups focusing on specific parts of the project, and/or involved with code development. Both kinds of collaborations could also involve jointly exploring funding opportunities from federal or philanthropic agencies. Please reach out to the PIs or Lead Software Scientist Jeff Wagner by email to discuss potential involvement.
How can I use the research products of the Open Force Field Consortium (papers, data, software)?
Everything that we develop will be fully open source under permissive licenses. Our codes are all distributed with the MIT or BSD-3 license, and written materials are made available under CC-BY 4.0.
I am interested in contributing some codes to the Consortium. Will I retain the right to use my codes for commercial research and products?
Because the MIT and BSD-3 software licenses permit commercial use, any codes distributed by the Consortium may be used commercially.
What molecular simulation packages will your force fields work in?
The reference implementation of the SMIRNOFF force field specification can produce parameterized small molecules in a variety of commonly supported formats, including support for OpenMM, AMBER, CHARMM, Gromacs, and NAMD, thanks to the open source conversion tools ParmEd and InterMol.
Where can I find more information about your development timeline?
See our science page for the latest scientific roadmap.
What is the difference between the Initiative and the Consortium?
The Open Force Field Initiative includes everyone supported by and/or working with the initiative; thus, we use the term “Initiative” to refer to the whole project and everyone involved, including commercial partners and scientific plans. The “Consortium” is the group of people and entities involved in the formal project/funding initiative.
