Problem with sdf reader.

Errors during load due to missing node extensions (Hydrogen Remover, Molecule Properties).
Could not find any extension(s) that provides the missing node(s).

I need Knime automatic workflow for the curation of chemical datasets.

Welcome to the forum @kastriotademi.

It seems to me that the sd reader is working fine. The errors you’re getting are from missing Indigo2 nodes.

Could you please tell me how to add indigo extensions?

The easiest way would be to go to the site I linked and drag and drop the yellow icon into KNIME


Still have the same problem…

I’m not sure what the screenshot is showing. Can you explain more about the problem you’re having?

What happened when you dragged and dropped the extension from the KNIME Hub?

Can you share the workflow file?
