-# de-forcefields
-Transferable Doube Exponential non-bonded potential for condensed phase simulations of small molecules
+# DE-Force Fields
+Transferable Double Exponential non-bonded potential for condensed phase simulations of small molecules.
+
+
+[![CI](https://github.com/jthorton/de-forcefields/actions/workflows/CI.yaml/badge.svg)](https://github.com/jthorton/de-forcefields/actions/workflows/CI.yaml)
+
+This repository contains general transferable force fields that use the Double Exponential functional form first proposed by [Brooks](http://aip.scitation.org/doi/10.1063/1.5107505).
+These force fields use the SMIRKS Native Open Force Field (SMIRNOFF) format.
+By convention these files use the `.offxml` file extension.
+The SMIRNOFF format has a [specification](https://openforcefield.github.io/standards/standards/smirnoff/) and is discussed in a [JCTC publication](https://doi.org/10.1021/acs.jctc.8b00640) and associated [pre-print](https://www.biorxiv.org/content/10.1101/286542v3).
+
+The [OpenFF Toolkit](https://github.com/openforcefield/openff-toolkit) (version >0.10.6, <0.11.0) provides a reference implementation of the SMIRNOFF format.
+In particular, the `ForceField` class is used to load SMIRNOFF-format force fields and the `create_openmm_system` method enables the parametrization of small molecules into OpenMM objects.
+[Smirnoff-plugins](https://github.com/openforcefield/smirnoff-plugins) provides a framework to extend the SMIRNOFF specification with custom force field functional forms such as the Double Exponential form used here, using a plugin system.
+See `smirnoff-plugins` for a list of the currently supported potentials.
+
+Detailed usage examples can be found in the OpenFF Toolkit repository.
+
+Each force field is currently available in two forms -- both with and without bond constraints to hydrogen. The default version of each force field (i.e. de-1.0.0.offxml) is suitable for typical molecular dynamics simulations with constrained bonds to hydrogen.
+The "unconstrained" version of each force field (i.e. de_unconstrained-1.0.0.offxml) should be used when single-point energies are a major concern (e.g. geometry optimizations) and when comparing the force field to QM data.
+
+| Filename | DOI | FF line | Release Date | Major format changes? |
+|---------------------------------------|------|------------|--------------|-----------------------|
+| `de-force-1.0.0.offxml` | TODO | DE-Force-1 | Feb 17, 2023 | No |
+| `de-force_unconstrained-1.0.0.offxml` | TODO | DE-Force-1 | Feb 17, 2023 | No |
+
+
+## Installation
+
+```shell
+conda install -c conda-forge de-forcefields
+```
+
+
+## Use
+
+Installing this package exposes an entry point that makes the `deforcefields/offxml/` directory easily accessible by other packages in the same Python installation.
+If the [OpenFF Toolkit](https://github.com/openforcefield/openff-toolkit) is installed, it will automatically detect and use this entry point:
+
+```python3
+>>> from openff.toolkit.typing.engines.smirnoff import ForceField
+>>> ff = ForceField('de-force-1.0.0.offxml', load_plugins=True)
+```
+
+Otherwise, the entry point can be accessed by querying the `openforcefield.smirnoff_forcefield_directory` entry point group.
+
+```python3
+>>> from pkg_resources import iter_entry_points
+>>> for entry_point in iter_entry_points(group='openforcefield.smirnoff_forcefield_directory'):
+... print(entry_point.load()())
+```
+
+
+# History
+
+Force fields in the `DE-Force-1` lines are descended from [OpenFF-2.0.0 Sage](https://doi.org/10.5281/zenodo.5214478).
+
+## General versioning guidelines
+
+Force fields moving forward will be called `name-X.Y.Z`
+
+* `X` denotes some major change in functional form or fitting strategy.
+* `Y` is the parameterization epoch / generation, or a minor change that can affect energy.
+* `Z` is a bugfix version -- e.g. something we've caught and corrected.

+The Versioneer
+==============
+
+* like a rocketeer, but for versions!
+* https://github.com/python-versioneer/python-versioneer
+* Brian Warner
+* License: Public Domain (Unlicense)
+* Compatible with: Python 3.7, 3.8, 3.9, 3.10 and pypy3
+* [![Latest Version][pypi-image]][pypi-url]
+* [![Build Status][travis-image]][travis-url]
+
+This is a tool for managing a recorded version number in setuptools-based
+python projects. The goal is to remove the tedious and error-prone "update
+the embedded version string" step from your release process. Making a new
+release should be as easy as recording a new tag in your version-control
+system, and maybe making new tarballs.
+
+
+## Quick Install
+
+Versioneer provides two installation modes. The "classic" vendored mode installs
+a copy of versioneer into your repository. The experimental build-time dependency mode
+is intended to allow you to skip this step and simplify the process of upgrading.
+
+### Vendored mode
+
+* `pip install versioneer` to somewhere in your $PATH
+ * A [conda-forge recipe](https://github.com/conda-forge/versioneer-feedstock) is
+ available, so you can also use `conda install -c conda-forge versioneer`
+* add a `[tool.versioneer]` section to your `pyproject.toml` or a
+ `[versioneer]` section to your `setup.cfg` (see [Install](INSTALL.md))
+ * Note that you will need to add `tomli; python_version < "3.11"` to your
+ build-time dependencies if you use `pyproject.toml`
+* run `versioneer install --vendor` in your source tree, commit the results
+* verify version information with `python setup.py version`
+
+### Build-time dependency mode
+
+* `pip install versioneer` to somewhere in your $PATH
+ * A [conda-forge recipe](https://github.com/conda-forge/versioneer-feedstock) is
+ available, so you can also use `conda install -c conda-forge versioneer`
+* add a `[tool.versioneer]` section to your `pyproject.toml` or a
+ `[versioneer]` section to your `setup.cfg` (see [Install](INSTALL.md))
+* add `versioneer` (with `[toml]` extra, if configuring in `pyproject.toml`)
+ to the `requires` key of the `build-system` table in `pyproject.toml`:
+ ```toml
+ [build-system]
+ requires = ["setuptools", "versioneer[toml]"]
+ build-backend = "setuptools.build_meta"
+ ```
+* run `versioneer install --no-vendor` in your source tree, commit the results
+* verify version information with `python setup.py version`
+
+## Version Identifiers
+
+Source trees come from a variety of places:
+
+* a version-control system checkout (mostly used by developers)
+* a nightly tarball, produced by build automation
+* a snapshot tarball, produced by a web-based VCS browser, like github's
+ "tarball from tag" feature
+* a release tarball, produced by "setup.py sdist", distributed through PyPI
+
+Within each source tree, the version identifier (either a string or a number,
+this tool is format-agnostic) can come from a variety of places:
+
+* ask the VCS tool itself, e.g. "git describe" (for checkouts), which knows
+ about recent "tags" and an absolute revision-id
+* the name of the directory into which the tarball was unpacked
+* an expanded VCS keyword ($Id$, etc)
+* a `_version.py` created by some earlier build step
+
+For released software, the version identifier is closely related to a VCS
+tag. Some projects use tag names that include more than just the version
+string (e.g. "myproject-1.2" instead of just "1.2"), in which case the tool
+needs to strip the tag prefix to extract the version identifier. For
+unreleased software (between tags), the version identifier should provide
+enough information to help developers recreate the same tree, while also
+giving them an idea of roughly how old the tree is (after version 1.2, before
+version 1.3). Many VCS systems can report a description that captures this,
+for example `git describe --tags --dirty --always` reports things like
+"0.7-1-g574ab98-dirty" to indicate that the checkout is one revision past the
+0.7 tag, has a unique revision id of "574ab98", and is "dirty" (it has
+uncommitted changes).
+
+The version identifier is used for multiple purposes:
+
+* to allow the module to self-identify its version: `myproject.__version__`
+* to choose a name and prefix for a 'setup.py sdist' tarball
+
+## Theory of Operation
+
+Versioneer works by adding a special `_version.py` file into your source
+tree, where your `__init__.py` can import it. This `_version.py` knows how to
+dynamically ask the VCS tool for version information at import time.
+
+`_version.py` also contains `$Revision$` markers, and the installation
+process marks `_version.py` to have this marker rewritten with a tag name
+during the `git archive` command. As a result, generated tarballs will
+contain enough information to get the proper version.
+
+To allow `setup.py` to compute a version too, a `versioneer.py` is added to
+the top level of your source tree, next to `setup.py` and the `setup.cfg`
+that configures it. This overrides several distutils/setuptools commands to
+compute the version when invoked, and changes `setup.py build` and `setup.py
+sdist` to replace `_version.py` with a small static file that contains just
+the generated version data.
+
+## Installation
+
+See [INSTALL.md](./INSTALL.md) for detailed installation instructions.
+
+## Version-String Flavors
+
+Code which uses Versioneer can learn about its version string at runtime by
+importing `_version` from your main `__init__.py` file and running the
+`get_versions()` function. From the "outside" (e.g. in `setup.py`), you can
+import the top-level `versioneer.py` and run `get_versions()`.
+
+Both functions return a dictionary with different flavors of version
+information:
+
+* `['version']`: A condensed version string, rendered using the selected
+ style. This is the most commonly used value for the project's version
+ string. The default "pep440" style yields strings like `0.11`,
+ `0.11+2.g1076c97`, or `0.11+2.g1076c97.dirty`. See the "Styles" section
+ below for alternative styles.
+
+* `['full-revisionid']`: detailed revision identifier. For Git, this is the
+ full SHA1 commit id, e.g. "1076c978a8d3cfc70f408fe5974aa6c092c949ac".
+
+* `['date']`: Date and time of the latest `HEAD` commit. For Git, it is the
+ commit date in ISO 8601 format. This will be None if the date is not
+ available.
+
+* `['dirty']`: a boolean, True if the tree has uncommitted changes. Note that
+ this is only accurate if run in a VCS checkout, otherwise it is likely to
+ be False or None
+
+* `['error']`: if the version string could not be computed, this will be set
+ to a string describing the problem, otherwise it will be None. It may be
+ useful to throw an exception in setup.py if this is set, to avoid e.g.
+ creating tarballs with a version string of "unknown".
+
+Some variants are more useful than others. Including `full-revisionid` in a
+bug report should allow developers to reconstruct the exact code being tested
+(or indicate the presence of local changes that should be shared with the
+developers). `version` is suitable for display in an "about" box or a CLI
+`--version` output: it can be easily compared against release notes and lists
+of bugs fixed in various releases.
+
+The installer adds the following text to your `__init__.py` to place a basic
+version in `YOURPROJECT.__version__`:
+
+ from ._version import get_versions
+ __version__ = get_versions()['version']
+ del get_versions
+
+## Styles
+
+The setup.cfg `style=` configuration controls how the VCS information is
+rendered into a version string.
+
+The default style, "pep440", produces a PEP440-compliant string, equal to the
+un-prefixed tag name for actual releases, and containing an additional "local
+version" section with more detail for in-between builds. For Git, this is
+TAG[+DISTANCE.gHEX[.dirty]] , using information from `git describe --tags
+--dirty --always`. For example "0.11+2.g1076c97.dirty" indicates that the
+tree is like the "1076c97" commit but has uncommitted changes (".dirty"), and
+that this commit is two revisions ("+2") beyond the "0.11" tag. For released
+software (exactly equal to a known tag), the identifier will only contain the
+stripped tag, e.g. "0.11".
+
+Other styles are available. See [details.md](details.md) in the Versioneer
+source tree for descriptions.
+
+## Debugging
+
+Versioneer tries to avoid fatal errors: if something goes wrong, it will tend
+to return a version of "0+unknown". To investigate the problem, run `setup.py
+version`, which will run the version-lookup code in a verbose mode, and will
+display the full contents of `get_versions()` (including the `error` string,
+which may help identify what went wrong).
+
+## Known Limitations
+
+Some situations are known to cause problems for Versioneer. This details the
+most significant ones. More can be found on Github
+[issues page](https://github.com/python-versioneer/python-versioneer/issues).
+
+### Subprojects
+
+Versioneer has limited support for source trees in which `setup.py` is not in
+the root directory (e.g. `setup.py` and `.git/` are *not* siblings). The are
+two common reasons why `setup.py` might not be in the root:
+
+* Source trees which contain multiple subprojects, such as
+ [Buildbot](https://github.com/buildbot/buildbot), which contains both
+ "master" and "slave" subprojects, each with their own `setup.py`,
+ `setup.cfg`, and `tox.ini`. Projects like these produce multiple PyPI
+ distributions (and upload multiple independently-installable tarballs).
+* Source trees whose main purpose is to contain a C library, but which also
+ provide bindings to Python (and perhaps other languages) in subdirectories.
+
+Versioneer will look for `.git` in parent directories, and most operations
+should get the right version string. However `pip` and `setuptools` have bugs
+and implementation details which frequently cause `pip install .` from a
+subproject directory to fail to find a correct version string (so it usually
+defaults to `0+unknown`).
+
+`pip install --editable .` should work correctly. `setup.py install` might
+work too.
+
+Pip-8.1.1 is known to have this problem, but hopefully it will get fixed in
+some later version.
+
+[Bug #38](https://github.com/python-versioneer/python-versioneer/issues/38) is tracking
+this issue. The discussion in
+[PR #61](https://github.com/python-versioneer/python-versioneer/pull/61) describes the
+issue from the Versioneer side in more detail.
+[pip PR#3176](https://github.com/pypa/pip/pull/3176) and
+[pip PR#3615](https://github.com/pypa/pip/pull/3615) contain work to improve
+pip to let Versioneer work correctly.
+
+Versioneer-0.16 and earlier only looked for a `.git` directory next to the
+`setup.cfg`, so subprojects were completely unsupported with those releases.
+
+### Editable installs with setuptools <= 18.5
+
+`setup.py develop` and `pip install --editable .` allow you to install a
+project into a virtualenv once, then continue editing the source code (and
+test) without re-installing after every change.
+
+"Entry-point scripts" (`setup(entry_points={"console_scripts": ..})`) are a
+convenient way to specify executable scripts that should be installed along
+with the python package.
+
+These both work as expected when using modern setuptools. When using
+setuptools-18.5 or earlier, however, certain operations will cause
+`pkg_resources.DistributionNotFound` errors when running the entrypoint
+script, which must be resolved by re-installing the package. This happens
+when the install happens with one version, then the egg_info data is
+regenerated while a different version is checked out. Many setup.py commands
+cause egg_info to be rebuilt (including `sdist`, `wheel`, and installing into
+a different virtualenv), so this can be surprising.
+
+[Bug #83](https://github.com/python-versioneer/python-versioneer/issues/83) describes
+this one, but upgrading to a newer version of setuptools should probably
+resolve it.
+
+
+## Updating Versioneer
+
+To upgrade your project to a new release of Versioneer, do the following:
+
+* install the new Versioneer (`pip install -U versioneer` or equivalent)
+* edit `setup.cfg` and `pyproject.toml`, if necessary,
+ to include any new configuration settings indicated by the release notes.
+ See [UPGRADING](./UPGRADING.md) for details.
+* re-run `versioneer install --[no-]vendor` in your source tree, to replace
+ `SRC/_version.py`
+* commit any changed files
+
+## Future Directions
+
+This tool is designed to make it easily extended to other version-control
+systems: all VCS-specific components are in separate directories like
+src/git/ . The top-level `versioneer.py` script is assembled from these
+components by running make-versioneer.py . In the future, make-versioneer.py
+will take a VCS name as an argument, and will construct a version of
+`versioneer.py` that is specific to the given VCS. It might also take the
+configuration arguments that are currently provided manually during
+installation by editing setup.py . Alternatively, it might go the other
+direction and include code from all supported VCS systems, reducing the
+number of intermediate scripts.
