We have updated the toolkit so it now includes the ability to parse and use the ambiguity definition and we have created a new API which allows you to add the chemistry engine of your choice. We have implemented two chemistry engines: CDK and MarvinBeans, but you can add your own. If you do, please consider donating the code back to the project so others can benefit.
HELM Toolkit v1.x
The HELM editor and HAbE are designed to work with the HELM toolkit v 1.x, so we are keeping this in place until we replace both with web-based versions.

Validation Tool
A basic UI has been developed which allows the user to convert HELM1 to HELM2 or JSON. This has the side-effect of providing a validation tool, since if the input HELM is not valid, it will not be converted.

As this is an open source project you are at liberty to replace MarvinBeans 5.0 with your preferred tool. If you do this, please consider donating the modified code base back to the project.
