Hi,
Thank you for uploading the code and the pretrained weights! I have one quick question.
Which mode of MGSSL from the paper does motif_based_pretrain/saved_models/pretrained.pth
correspond to?
Hello, Zhang:
When I run the ''model.py'' , only "gin_type" = "gin" work successfully, and other models, including gat, gcn, graphsage and attentivefp are fail to work. All of them were base on your code. I am appreciate you will resoponse to me.
The traceback file is attached.

Hi zaixizhang, Thanks for sharing your nice works!
I have some questions about generating cliques and bonds in your code.
Is there any reason to set MST_MAX_WEIGHT to 100?(motif_based_pretrain > util > chemutils.py)
1-1. If not, how does the MST_MAX_WEIGHT effect to generated cliques?(i.e. If MST_MAX_WEIGHT raises, it causes almost infinite number of motifs?)
In MolTree, When the number of edges connecting BRICS cliques is less then 1, Tree decomp overwrites cliques and edges. Does it okay to change the threshold 1 to any small integer like 2 or 3?
Sincerely,
JongKook Heo
Dear author, I run the mol_tree.py to preprocess the dataset and generate clique.txt, but it throws the KekulizeException for molecules such as Cc1c(/C=C/c2cc(Br)ccn2)c(O)n2c(nc3ccccc32)c1C#N. I use the decomposition modules on other datsets, it make the same exceptions, can you update the code or give some advice?
def get_smiles(mol):
return Chem.MolToSmiles(mol, kekuleSmiles=True)
smiles = Chem.MolFragmentToSmiles(mol, atoms, kekuleSmiles=True)
Why does reading smiles require kekule format?
Is it possible not to use kekule format?
Hi is there an easy way to extract just the fingerprints given the pretrained model?
Hi, I wonder if there are ovelapping atoms between motifs in one molecule?
I run the following script
from moltree import MolTree
smiles = "O=C1[C@@H]2C=C[C@@H](C=CC2)C1(c1ccccc1)c1ccccc1"
mol = MolTree(smiles)
atom_count = 0
for c in mol.nodes:
atom_count += c.mol.GetNumAtoms()
print(c.mol.GetNumAtoms())
print(c.clique)
print(f"atoms in original mol: {mol.mol.GetNumAtoms()}, atoms in motifs: {atom_count}")
And the output is:
2

[9, 10]

Hello!
I'm trying to run mol_tree.py, but I'm getting KekulizeException: error.
Is it a problem about rdkit version?

Thank you!
Dear author, in the paper the final loss is the sum of atom, bond and motif. I cannot find the loss of atom and bond in the source code. So what is the final loss function of MGSSL?

请问该怎么解决
Hey friend, I wanna how to get the dataset?
运行代码:

sys.path.append('./util/')
from mol_tree import MolTree
data_mol_tree = []
for idx in range(5):
smiles = data[idx]
mol_tree = MolTree(smiles)
mol_tree.recover()
mol_tree.assemble()
data_mol_tree.append(mol_tree)
