Datamol is a python library to work with molecules.

Added:

• Add PDB read/writer functions: dm.to_pdbblock(), dm.read_pdbblock(), dm.read_pdbfile(), dm.to_pdbfile()

Changed:

• Improve output type in to_df.`

Authors:

• Hadrien Mary

Added:

• Add multiple utilities to work with mapped SMILES with hydrogens.
• Add dm.clear_atom_props() to remove atom's properties.
• Add dm.clear_atom_map_number() to remove the atom map number property.
• Add dm.get_atom_positions() to retrieve the atomic positions of a conformer of a molecule.
• Add dm.set_atom_positions() to add a new confomer to a molecule given a list of atomic positions.

Changed:

• Add new arguments to dm.to_mol: allow_cxsmiles, parse_name, remove_hs and strict_cxsmiles. Refers to the docstring for the details.
• Set copy to True by default to dm.atom_indices_to_mol().
• Allow to specify the property keys to clear in dm.clear_mol_props(). If not set, the original default beahviour is to clear everything.

Authors:

• Hadrien Mary

Fixed:

• Ensure rdkit 2021.03 works with latest datamol. The support is not "official" but only a single function must be adapted so it's ok.

Authors:

• Hadrien Mary

Added:

• Support for max_num_mols in dm.read_sdf(). Useful when files are large and debugging code.
• Support for returning the invalid molecules in dm.read_sdf. Useful when we need to know which one failed.
• Support for more compression formats when reading SDF files using fssep.open(..., compression="infer").
• Add CODEOWNERS file.
• Add dm.descriptors.n_spiro_atoms and dm.descriptors.n_stereo_centers_unspecified.

Changed:

• Overload output types for dm.read_sdf and dm.data.*.
• Reduce tests duration (especially in CI).

Authors:

• DomInvivo
• Hadrien Mary

Changed:

• Add a comment recommending to not use the SMI file format.

Fixed:

• Fix a bug when reading a remote file with dm.read_smi().

Authors:

• Hadrien Mary

Added:

• dm.Atom and dm.Bond types.

Authors:

• Hadrien Mary

Added:

• Added argument product_index in select_reaction_output. It allows to return all products and a product of interest by the index.

Fixed:

Authors:

• Hadrien Mary
• Lu Zhu

Changed:

• Bump upstream GH actions versions.
• dm.fs.copy_dir now uses the internal fsspec copy when the two source and destination fs are the same. It makes the copy much faster.

Fixed:

• Use os.PathLike to recognize a broader range of string-based path inputs in the dm.fs module. It prevents file objects such as py._path.local.LocalPath not being recognized as path.

Fixed:

• Missing header in the fragment tutorial.

Authors:

• energies output along with delta-energy to lowest energy conformer

Changed:

• API of dm.conformers.generate() to support choice of forcefield. In addition ewindow and eratio flags added to reject high energy conformers, either on absoute scale, or as ratio to rotatable bonds

• Improve documentation for dm.standardize_mol()
• Multiple various docstring and typing improvments.
• Embed the cdk2.sdf and solubility_*.sdf files within the datamol package to prevent issue with the RDKit config dir.
• Enable strict mode on the documentation to prevent any issues and inconsistency with the types and docstrings of datamol.
• Refactor micromamba CI to use latest and simplify it.

Removed:

• Remove unused and unmaintained dm.actions and dm.reactions module.
• Remove copy args from add_hs and remove_hs (RDKit already returns copies).
