The HELM project has developed a range of opensource tools which demonstrate what can be done with the notation.

HELM Web editor

Enables the user to create HELM strings by dragging and dropping monomers onto a sketchpad. Can interpret HELM strings or single letter sequences of natural monomers.


HELM Antibody Editor (HAbE)

Originally developed by Roche for internal use, they kindly open-sourced it for the community in 2018.

The antibody editor uses a Blast search to identify domains. The editor displays the domains and can manipulate the structures, creating Cys-Cys bonds and make other edits very flexibly due to the underlying HELM notation.


HELM Toolkit

A Java-based toolkit that creates webservices that can be accessed by third party tools.


Search Tool

In 2017/18 Eva Bültel (Hamburg University supervised by quattro research) wrote her masters thesis on searching structures encoded in HELM.
