|---|---|
| fgutils.torch | torch>=2.5 |
Installation
You can install FGUtils using pip.
pip install fgutils
Getting Started
For a comprehensive description of FGUtils features read through the documentation. However, querying the functional groups for a molecule like acetylsalicylic acid is as simple as running the following:
>>> from fgutils import FGQuery
>>>
>>> smiles = "O=C(C)Oc1ccccc1C(=O)O" # acetylsalicylic acid
>>> query = FGQuery()
>>> query.get(smiles)
[('ester', [0, 1, 3]), ('carboxylic_acid', [10, 11, 12])]
The output is a list of tuples containing the functional group name and the corresponding atom indices.
