SDF Extractor

This node allows you to extract the different parts an SDF molecule is made up of - Ctab block, Molfile block and data properties - into columns. The properties will be extracted into different columns. In order to find out, which properties are present in the SDF structures, the node will by default scan the first 100 structures. If this is not enough to determine all properties and their types, you can enable a full scan of the input table.

Dialog Options

SDF column
The column containing the SDF molecules.
Extract properties
Select this, if you want to extract the data properties into different columns
Scan whole table
Scans the full input table instead of the first 100 rows in order to determine the properties and their types
Extract Molfile block
Select this, if you want to extract the Molfile block into a column
Molfile column name
The new column's name that contains the Molfile blocks afterwards
Extract Ctab block
Select this, if you want to extract the Ctab block into a column
Ctab column name
The new column's name that contains the Ctab blocks afterwards

Ports

Input Ports
