From 53bf380fb8974c550a713dfcd1d9e8587e02ac58 Mon Sep 17 00:00:00 2001 From: JacksonBurns Date: Sun, 25 May 2025 17:42:02 -0400 Subject: [PATCH 01/73] Use `rdkit` for SSSR and RCs (bug fix + Python upgrade) Currently we use `RingDecomposerLib` for finding the Smallest Set of Smallest Rings and getting the Relevant Cycles. This package does not support Python 3.10+ and is thus blocking further upgrades to RMG. @knathanm in particular is looking to get RMG to Python 3.11 so as to add support for ChemProp v2. I believe we can just use RDKit to do these operations instead. The original paper mentions that the functionality was being moved upstream to RDKit. With the help of AI I've taken just a first pass at reimplementing, with the special note that: - I opted to use the Symmetric SSSR in place of the 'true' SSSR. This is because the latter is non-unique (see [RDKit's "The SSSR Problem"](https://www.rdkit.org/docs/GettingStartedInPython.html#the-sssr-problem)). This should actually resolve https://github.com/ReactionMechanismGenerator/RMG-Py/issues/2562 - I need to read more about the "Relevant Cycles" This PR will be a draft for now, as it is predicated on Python 3.9 already being available (which it nearly is in https://github.com/ReactionMechanismGenerator/RMG-Py/pull/2741) --- .github/workflows/CI.yml | 2 +- environment.yml | 1 - rmgpy/molecule/graph.pyx | 107 ++++++++++++++++++--------------------- utilities.py | 17 ------- 4 files changed, 49 insertions(+), 78 deletions(-) diff --git a/.github/workflows/CI.yml b/.github/workflows/CI.yml index e815da269d9..228d18a227c 100644 --- a/.github/workflows/CI.yml +++ b/.github/workflows/CI.yml @@ -63,7 +63,7 @@ jobs: strategy: fail-fast: false matrix: - python-version: ["3.9"] + python-version: ["3.9", "3.10", "3.11", "3.12"] os: [macos-13, macos-latest, ubuntu-latest] include-rms: ["", "with RMS"] exclude: diff --git a/environment.yml b/environment.yml index da840c1ab48..200c853c60c 100644 --- a/environment.yml +++ b/environment.yml @@ -84,7 +84,6 @@ dependencies: # bug in quantities, see: # https://github.com/ReactionMechanismGenerator/RMG-Py/pull/2694#issuecomment-2489286263 - conda-forge::quantities !=0.16.0,!=0.16.1 - - conda-forge::ringdecomposerlib-python # packages we maintain - rmg::pydas >=1.0.3 diff --git a/rmgpy/molecule/graph.pyx b/rmgpy/molecule/graph.pyx index 207470c4e52..ace47e2d707 100644 --- a/rmgpy/molecule/graph.pyx +++ b/rmgpy/molecule/graph.pyx @@ -35,7 +35,7 @@ are the components of a graph. import itertools -import py_rdl +from rdkit import Chem from rmgpy.molecule.vf2 cimport VF2 @@ -971,68 +971,57 @@ cdef class Graph(object): cpdef list get_smallest_set_of_smallest_rings(self): """ - Returns the smallest set of smallest rings as a list of lists. - Uses RingDecomposerLib for ring perception. - - Kolodzik, A.; Urbaczek, S.; Rarey, M. - Unique Ring Families: A Chemically Meaningful Description - of Molecular Ring Topologies. - J.

This commit makes it so that if the kekulization step fails during sanitization, then RDKit will try to sanitize with less stringent sanitization criteria. This was necessary because some species from adjacency lists would pop up and crash out due to failed sanitization. --- rmgpy/molecule/converter.py | 11 ++++++++--- 1 file changed, 8 insertions(+), 3 deletions(-) diff --git a/rmgpy/molecule/converter.py b/rmgpy/molecule/converter.py index d2027baf559..ce01a777bb9 100644 --- a/rmgpy/molecule/converter.py +++ b/rmgpy/molecule/converter.py @@ -38,6 +38,7 @@ import cython # Assume that rdkit is installed from rdkit import Chem +from rdkit.Chem.rdchem import KekulizeException, AtomKekulizeException # Test if openbabel is installed try: from openbabel import openbabel @@ -100,7 +101,7 @@ def to_rdkit_mol(mol, remove_h=True, return_mapping=False, sanitize=True, save_o rd_bonds = Chem.rdchem.BondType # no vdW bond in RDKit, so "ZERO" or "OTHER" might be OK orders = {'S': rd_bonds.SINGLE, 'D': rd_bonds.DOUBLE, 'T': rd_bonds.TRIPLE, 'B': rd_bonds.AROMATIC, - 'Q': rd_bonds.QUADRUPLE, 'vdW': rd_bonds.ZERO, 'H': rd_bonds.HYDROGEN, 'R': rd_bonds.OTHER} + 'Q': rd_bonds.QUADRUPLE, 'vdW': rd_bonds.ZERO, 'H': rd_bonds.HYDROGEN, 'R': rd_bonds.UNSPECIFIED} # Add the bonds for atom1 in mol.vertices: for atom2, bond in atom1.edges.items(): @@ -110,7 +111,7 @@ def to_rdkit_mol(mol, remove_h=True, return_mapping=False, sanitize=True, save_o index2 = atoms.index(atom2) if index1 < index2: order_string = bond.get_order_str() - if order_string is None and 1.0 < bond.get_order_num() < 2.0: + if order_string is None: order = rd_bonds.UNSPECIFIED else: order = orders[order_string] @@ -128,7 +129,11 @@ def to_rdkit_mol(mol, remove_h=True, return_mapping=False, sanitize=True, save_o if sanitize == True: Chem.SanitizeMol(rdkitmol) elif sanitize == "partial": - Chem.SanitizeMol(rdkitmol, sanitizeOps=Chem.SANITIZE_ALL ^ Chem.SANITIZE_PROPERTIES) + try: + Chem.SanitizeMol(rdkitmol, sanitizeOps=Chem.SANITIZE_ALL ^ Chem.SANITIZE_PROPERTIES) + except (KekulizeException, AtomKekulizeException): + logging.warning("Kekulization failed; sanitizing without Kekulize") + Chem.SanitizeMol(rdkitmol, sanitizeOps=Chem.SANITIZE_ALL ^ Chem.SANITIZE_PROPERTIES ^ Chem.SANITIZE_KEKULIZE) if remove_h: rdkitmol = Chem.RemoveHs(rdkitmol, sanitize=sanitize) if return_mapping: From 8b34c30e3a0f4f02552a8b9b8022ab2675715793 Mon Sep 17 00:00:00 2001 From: jonwzheng Date: Thu, 24 Jul 2025 15:07:54 -0400 Subject: [PATCH 31/73] update scipy simps to sipmson simps was deprecated in scipy 1.6 in favor of simpson.

This commit checks whether a simpler approach would work: just checking if the atom.label is either 'R' or 'L'. If that's the case, we can then make the change. --- rmgpy/molecule/converter.py | 14 ++++++++++++-- 1 file changed, 12 insertions(+), 2 deletions(-) diff --git a/rmgpy/molecule/converter.py b/rmgpy/molecule/converter.py index 35196d178e6..8b0667d71b7 100644 --- a/rmgpy/molecule/converter.py +++ b/rmgpy/molecule/converter.py @@ -66,7 +66,7 @@ def to_rdkit_mol(mol, remove_h=True, return_mapping=False, sanitize=True, """ if ignore_bond_orders and sanitize: raise ValueError("If ignore_bond_orders is True, sanitize must be False") - from rmgpy.molecule.fragment import Fragment + from rmgpy.molecule.fragment import Fragment, CuttingLabel # Sort the atoms before converting to ensure output is consistent # between different runs if not save_order: @@ -97,14 +97,24 @@ def to_rdkit_mol(mol, remove_h=True, return_mapping=False, sanitize=True, # Check if a cutting label is present.

As far as I can tell, cutting labels can only be "L" or "R". I had a previous commit that checked this is equivalent, and by running the unit tests and regression tests could not find a counterexample. This check is much simpler, and about 200 times faster, than the previous call to detect_cutting_label. Also simplified the dictionary structure. --- rmgpy/molecule/converter.py | 37 +++++++++---------------------------- 1 file changed, 9 insertions(+), 28 deletions(-) diff --git a/rmgpy/molecule/converter.py b/rmgpy/molecule/converter.py index 8b0667d71b7..ae005cb25b6 100644 --- a/rmgpy/molecule/converter.py +++ b/rmgpy/molecule/converter.py @@ -73,7 +73,7 @@ def to_rdkit_mol(mol, remove_h=True, return_mapping=False, sanitize=True, mol.sort_atoms() atoms = mol.vertices rd_atom_indices = {} # dictionary of RDKit atom indices - label_dict = {} # store label of atom for Framgent + label_dict = {} # For fragment cutting labels.

Previously, if you call to_rdkit_mol on a Fragment, it would always return the mapping, but if you called it on a Molecule, it would by default not. Now if you call it with return_mapping=False (or not specified) then it doesn't return the mapping, and if you call it with return_mapping=True, then it does. Internally, it calls converter.to_rdkit_mol with return_mapping=True, but doesn't pass it back unless asked. Now the behavior of thing.to_rdkit_mol() is the same whether thing is a Molecule or a Fragment (which is a subclass of Molecule). Should reduce number of warnings, eg. when drawing fragments.
