Overview

OpenSMOG is a Python library for performing molecular dynamics simulations using Structure-Based Models. OpenSMOG uses the OpenMM. 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 -OpenSMOG). Details on how to generate OpenSMOG-compatible force fields files can be found in the SMOG2 User Manual.

When using OpenSMOG and SMOG2, please use the following references.

Installation

The OpenSMOG library can be installed via conda or pip, or compiled from source (GitHub).

Install via conda

The code below will install OpenSMOG from conda-forge.

conda install -c conda-forge OpenSMOG

Install via pip

The code below will install OpenSMOG from PyPI.

pip install OpenSMOG

Install OpenMM

The OpenSMOG library uses OpenMM API to run the molecular dynamics simulations. These requirements can be met by installing the following packages from the conda-forge channel:

conda install -c conda-forge openmm

The following are libraries required for installing OpenSMOG:

Installing SMOG2

The inputs OpenSMOG simulations are generated using SMOG2 (version 2.4 and later). Here, there is a quick installation guide based on conda (Linux and Windows-WSL only).

First, download SMOG 2 (v2.4, or later) at smog-server.org

Second, create a new conda environment and activate it (called smog2.4, but name as appropriate):

conda create --name smog2.4 perl
conda activate smog2.4

Next, it is necessary to install a few Perl modules:

conda install -c bioconda perl-xml-simple perl-xml-libxml java-jdk
conda install -c eumetsat perl-pdl
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.

which perl

Then load and test the smog2 installation:

source configure.smog2
./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.
