WebNov 14, 2024 · Any molecular fragmentation scheme can be used, as long as it doesn’t cut rings (e.g. BRICS or RECAP ). Many atom typing schemes could be used. ... Assembly of molecular fragments in Python using RDKit is the slowest method here (\(\sim \) 1685 molecule/s). Editing a molecular graph (RWMol class in RDKit) is not so efficient. WebMar 14, 2015 · Hi Chris, You're missing one step: BRICS.BRICSBuild() is expecting molecules, not SMILES. If you add a call to Chem.MolFromSmiles() you should get what you want : In [12]: mcat = [Chem.MolFromSmiles(x) for x in catalog] In [13]: ms = BRICS.BRICSBuild(mcat) In [14]: for m in ms: print Chem.MolToSmiles(m) c1ncnc( … dwg to pdf converter pro https://ultranetdesign.com

FragmentOnBonds () will fragment a molecule given a list of bond identifiers. In default use it attaches a new "dummy" atom (what I've been calling a wildcard atom) to the atoms at the end of each broken bond. It will also set the isotope label for each newly created dummy atom to the atom index of the atom to which it is attached.

[1] The algorithm followed is: The molecule’s distance bounds matrix is calculated based on the connection table and a set of rules. The bounds matrix is smoothed using a triangle-bounds smoothing algorithm.
