Molecule standardisers

CATEGORY

Transform

SOURCE

RDKit

DESCRIPTION

Two cells performing molecular standardisation using the MolVS and Flatkinson standardisers.

INPUTS

A Dataset of Molecules

OUTPUTS

A Dataset of Molecules

OPTIONS

RDKIt version Which version of RDKit to use

ADDITIONAL INFO

Implemented in RDKit using sanifier.py from the Pipelines project.

Note: These are initial versions of molecule standardisers. Functionality is likely to change.

MolVStandardiser is based on code developed by Matt Swain and can be found here.

FlatkinsonStandardiser is based on code developed by Francis Atkinson and can be found here.

The aim is to provide alternative standardisers that can be used for different purposes. Its likely we will provide multiple configurations for different purposes

Output

Each input molecule is transformed according to the standardiser’s rules. The output is the transformed molecule, or the input molecule if no transformations are applied. For each input molecule one molecule is output.

A field name “Standardised” is added to the output molecules to indicate what was done. There are 3 values:

  • True - the molecule was transformed
  • False - the molecule was not transformed
  • Error - an error occurred during standardisation and the input molecule is returned without any changes
