Hydrogen Remover

Indigo extensions for KNIME Workbench version 2.0.0.qualifier by EPAM Systems, Inc.

Supported types:

  • Molecule: String, SDF, Smiles, CML, Mol, InChI
  • Reaction: String, RXN, SMILES

The node is based on the Indigo cheminformatics toolkit.

Options

Target Column
The column that contains molecules or reaction structures.
Append Column
Appends a new structure column (with the name as specified in the text field) if checked, replaces the original column otherwise.
Input type
Treat input as: a molecule, a reaction.
Treat X as pseudoatom
Treat the "X" atoms in Molfiles as pseudoatoms, not as "any halogen" query atoms.
Ignore stereochemistry errors
Ignore incorrectly specified stereochemistry on input structures, rather than sending the structures with stereochemistry errors to the "invalid molecules" table.

Input Ports

Table containing molecule or reaction structures.

Output Ports

The same as input, but with explicit hydrogens removed.
