It is a python (3.5+) module for analysing alchemical free energy simulations based on a given pertubration map. The tool works well with SOMD output.
with pip:
pip install freenrgworkflows
from github:
git clone git@github.com:michellab/freenrgworkflows.git
cd freenrgworkflows
python setup.py install
To test the installation from the github repository you can use the pytest frame work by typing:
pytest --verbosity 1 tests
in the root directory, i.e. freenrgworkflows
Networkanalysis provides both a simple API and a commandline tool in order to extract relative free energies from a large number of perturbations. The main script can be found in the bin directory and run in the following way:
python run_networkanalysis.py --help
Gives information on the command line options available. An example usage can loook like this:
python run_networkanalysis.py ../tests/io/summary_r1.csv --target_compound FXR45 -o ~/Desktop/blub.dat -e ../tests/io/ic50_exp.dat --stats --generate_notebook
summary_r1.csv is an collated output of analyse_freenrg mbar from SOMD, the target compound is randomly selected. The output file can be anything really, such as blub.dat written to the computers desktop. If you want to compare experiments to simulations you will need to provide a file containing IC50s on the commandline or kDs with the API. The flag --generate_notebook will generate a default jupyter notebook running the analysis from a notebook including plots comparing the experimental and computed free energies. The generated notebook can be opened using jupyter notebook ~/Desktop/blub.ipynb
