Register for the Automated Topology Builder (ATB) and Repository

Registration is required before molecules can be submitted and topologies downloaded.

You must indicate your intended use.

Academic: Access to the ATB as an academic user is only available for users from publicly funded teaching or research institutions. Any molecule submitted to the ATB as an academic user will be made publicly available.

Commercial: All other users of the ATB should register as commercial. Commercial access is made available under either a license or a collaborative agreement on a case-by-case basis. Commercial users (or academic users operating under a collaborative agreement) can restrict access to molecules they submit, associate with groups of existing users and gain access to additional functionality depending on the nature of the agreement.

If you are uncertain whether you should register as an academic or a commercial user please select commercial.
