Since its launch in 2011 the ATB has grown dramatically driven by you the users.
We are now asking for your help in planning the next phase of the project.
The survey will only take 5 minutes and can be accessed here: ATB User Survey
Your feedback will help understand how:
Tautomers (Beta Test) for molecules in clinical phase 4 trials ≤ 30 atoms.
Display tautomers for e.g. (+)-S,S-Ethambutol.

The Automated Topology Builder (ATB) and Repository has been developed and is currently maintained with support from the University of Queensland (UQ), the Australian Research Council (ARC) and the Queensland Cyber Infrastructure Foundation (QCIF). Access to the ATB is provided free to academic users from publically funded teaching or research institutions. Access for academic use is conditional on: i) any molecule submitted to the ATB being made publically available and ii) the source of any material downloaded from the ATB being appropriately acknowledged in any publications or other forms in which research using this material is disseminated.
Use of the ATB by other parties, or academic users wishing to restrict the access of others to specific molecules, is considered to be commercial in nature. Commercial access is available by licence or collaborative agreement. Parties interested in commercial licencing or other arrangements should contact Prof Alan E. Mark at the address provided at the bottom of the page.
See the FAQ page to get started.
Tutorials for common tasks on the ATB are currently being developed, the first of which is available here: How to View an Existing Molecule
