HELM (Hierarchical Editing Language for Macromolecules) enables the representation of a wide range of biomolecules…
…whose size and complexity render existing small-molecule and sequence-based informatics methodologies impractical or unusable.
HELM is compact and flexible.
Draw and convert structures into HELM using the editor.
Antibody Editor (HAbE)
Visualise antibodies, manipulate the structures and analyse domains.
Create your own applications using the functionality in the toolkit.
HELM relies on an active voluntary community. We are currently supported by the following companies.
