The script empiricalSES.py predicts log D as in submission #49. It estimates:

1. free energy of hydration
2. free energy of solvation in cyclohexane
3. cyclohexane/water partition coefficient

Requirements / dependencies

• Works on Linux
• Python
• openbabel (v2.3.2 available through apt-get)
• python-openbabel (available through apt-get)
• python-numpy (available through apt-get)
• MSMS (http://mgltools.scripps.edu/downloads)

Setup

1. Download the script (empiricalSES.py)
2. Install the dependencies
3. Edit line 4 in empiricalSES.py to specify the path to MSMS binary

Usage examples

python /path/to/empiricalSES.py --help
python /path/to/empiricalSES.py molecule.sdf
python /path/to/empiricalSES.py mymols/*.mol2
