email: job name: (optional) execution log: short detailed PDB ids: upload PDBs: Additional Options... similarity threshold:   angle tolerance: span tolerance:   maximum inter-core distance: The search may take a few minutes depending on the number and size of the proteins and the parameters you specify. Your request will be processed in the order that it was received. The results will be sent to the email you provide.

You can either enter the pdb id's of the proteins you want to align, or upload them as pdb files. The pdb id's can include a 5th letter for the chain code, in addition to the 4-letter pdb code (e.g., 1cseE). If no chain code is provided, the first chain in the pdb is used. If you are uploading a pdb file, you need to ensure that the chain you want to use is the first (or only) chain in the pdb file. The data in the pdb file must be in standard PDB format. The Results page contains sample datasets and their results. Please feel free to contact us at for questions or help.
