Molecular columns converted to string format after python scripting node

Hi all,
when I work on tables containing molecules, everytime I am using a python script node to work on any column other than molecular columns, the output table from the python script node has the molecular columns converted in string format. So I always need to recast these columns to molecular format format (e.g. sdf or smiles). Is there a way to avoid this feature to append ?
Thank you in advance for any help.
Best regards.

Hi Thierry,

Apologies for not coming back to you sooner.
Unfortunately, currently it is not possible to preserve the appropriate chemistry type using the Python Script nodes. But it is an open feature request and our developers are working on the solution.
You could try the Java Snippet node that allows to explicitly define the type of each output column.

Hope it helps.
