The HELM project team is happy to announce the release of an open source web-editor to complement its existing suite of software. This web-editor is designed to support organisations that do not wish to deploy a thick client.
This is an initial release and the functionality will be extended in further releases during 2017. Current functionality includes:
- HELM 1 support
- The ability to use the supplied monomer libraries to draw macromolecules, visualise them as sequences or atom/bond structures and calculate properties.
- Import/export of HELM and xHELM.
- A limited set of rules that allow you to manipulate the structure.
Trial version
A demo version is available for you to try the functionality. Please note that this is for trial use only, if you want to use it in a production environment please take the code and deploy it on your own servers.

The demo web-editor uses the monomer set supplied with the old HELM editor. However, the code includes both this and an alternative set curated by Ionis with a larger range of nucleotide monomers.
