# Pygmx
|
|
|
|
A Cython wrapper for the shared library of GROMACS 5.1.
|
|
|
|
## Installation
|
|
|
|
Pygmx requires some python packages and an installation of GROMACS 5.1.
|
|
|
|
### Python requirements
|
|
|
|
* Cython
|
|
* NumPy
|
|
|
|
### Gromacs installation
|
|
|
|
#### Using a module
|
|
|
|
If gromacs is installed as a module in your system, run
|
|
|
|
module load gromacs/5.1
|
|
|
|
and skip to the section *Installing pygmx*.
|
|
|
|
#### Manual setup
|
|
|
|
The shared library of GROMACS 5.1and the corresponding c++ header files need to be present on the system.
|
|
If the shared library is installed globally, the environment variable `LD_LIBRARY_PATH` must be set.
|
|
The installation process will look for the header files by replacing any `lib` folder
|
|
in `LD_LIBRARY_PATH` with `include`.
|
|
|
|
If no header files are present, simply pull the submodule `gromacs` in this repository.
|
|
To build the shared library, follow the [official installation instructions](http://manual.gromacs.org/documentation/5.1.2/install-guide/index.html),
|
|
starting with step 4 (creating a build directory).
|
|
|
|
### Installing pygmx
|
|
|
|
When the requirements are met, the installation should be easy.
|
|
Navigate to the top folder of the repository and run the command
|
|
|
|
python setup.py install
|
|
|
|
This builds the cython modules and installs them into the local python distribution.
