Indigo Similarity Bug

[Mohamed El-Dirany]

Hi,

For some reason I'm facing a bug when I'm dealing with trying to get similarities between a large amount of molecules. I have the following code:

>>> from indigo import *
>>> indigo = Indigo()
       molecules.append(mol)
        except Exception as err:
            print(smiles)
            print(err)
            continue
>>>
>>> molecules = []
>>>
>>> with open("../CompoundsInGI50.txt") as f:
...     for line in f:
...         linesplit = line.split(",")
...         number = linesplit[0]
...         smiles = linesplit[1]
...         try:
...             mol = indigo.loadMolecule(smiles)
...             molecules.append(mol)
...         except Exception as err:
...             print(smiles)
...             print(err)
...             continue
...
>>> len(molecules)
31429
>>> molecules[0]
<indigo.IndigoObject object at 0x2b9540b43e48>
>>> molecules[0]
<indigo.IndigoObject object at 0x2b9540b43e48>
>>> indigo.similarity(molecules[0], molecules[0], 'tversky')
0.0

So as you can see, for some reason, finding the similarity between the same molecule gives me 0, and the similarity ALWAYS gives me 0 in this specific case. When I try loading another molecule manually, it doesn't seem to run into this error. Is there any possible reason why this might be happening or how to fix it?

Best,

Mohamed
