OpenSMOG is a Python library for performing molecular dynamics simulations using Structure-Based Models. OpenSMOG uses the OpenMM <http://openmm.org/>
_. Python API, which supports a wide variety of potential energy functions, including those that are commonly employed in C-alpha and all-atom models.
While it is possible to use this library in a standalone fashion, it is expected that users will generate input files using the SMOG2 software (version 2.4, or later, with the flag :code:-OpenSMOG
). Details on how to generate OpenSMOG-compatible force fields files can be found in the SMOG2 User Manual <https://smog-server.org/smog2/>

</p>
When using OpenSMOG and SMOG2, please use the following references <https://opensmog.readthedocs.io/en/latest/Reference/citing.html>
__.
The OpenSMOG library can be installed via conda <https://conda.io/projects/conda/>
or pip <https://pypi.org/>
, or compiled from source (GitHub) <https://github.com/junioreif/OpenSMOG>
_.
The code below will install OpenSMOG from conda-forge <https://anaconda.org/conda-forge/OpenSMOG>
_.
.. code-block:: bash
conda install -c conda-forge OpenSMOG
The code below will install OpenSMOG from PyPI <https://pypi.org/project/OpenSMOG/>
_.
.. code-block:: bash
pip install OpenSMOG
The OpenSMOG library uses OpenMM <http://openmm.org/>
_ API to run the molecular dynamics simulations.
These requirements can be met by installing the following packages from the conda-forge channel <https://conda-forge.org/>
__:
.. code-block:: bash
conda install -c conda-forge openmm
The following are libraries required for installing OpenSMOG:
- `Python <https://www.python.org/>`__ (>=3.6)
- `NumPy <https://www.numpy.org/>`__ (>=1.14)
- `lxml <https://lxml.de/>`__ (>=4.6.2)
The inputs OpenSMOG simulations are generated using SMOG2 <https://smog-server.org/smog2>
(version 2.4 and later). Here, there is a quick installation guide based on conda <https://conda.io/projects/conda/>
(Linux and Windows-WSL only).
First, download SMOG 2 (v2.4, or later) at smog-server.org <https://smog-server.org/smog2/>
__
Second, create a new conda environment and activate it (called smog2.4, but name as appropriate):
.. code-block:: bash
conda create --name smog2.4 perl
.. code-block:: bash
conda activate smog2.4
Next, it is necessary to install a few Perl modules:
.. code-block:: bash
conda install -c bioconda perl-xml-simple perl-xml-libxml java-jdk
.. code-block:: bash
conda install -c eumetsat perl-pdl
.. code-block:: bash
perl -MCPAN -e 'install XML::Validator::Schema'
Add the Perl and smog2 path into the configure.smog2 file (described in the README that comes with SMOG 2).
.. hint:: Use the following command line to find out which installed Perl is being used.
.. code-block:: bash
which perl
Then load and test the smog2 installation:
.. code-block:: bash
source configure.smog2
.. code-block:: bash
./test-config
As described in the SMOG 2 manual, it is highly recommended that you also download smog-check and run all checks before using the SMOG 2 software.
After you have installed OpenSMOG (and optionally SMOG 2), you can check to see that the code is functioning properly using OpenSMOGcheck. To run the check, you just need to run the following commands (from within python):
.. code-block:: bash
from OpenSMOG import SBM
SBM.opensmogcheck()
If smog2 is in your path, then this will check compatibility of SMOG2 and OpenSMOG. If smog2 is not in your path, it will simply evaluate the energies for representative models/configurations and compare them to reference values.
