DASH

Input Requirements

Input structure must be a PDB or mmCIF file.
Input structure may be compressed with GZip but size must be less than 500 MB (compressed or uncompressed).
Chain ID is required for structures with more than 1 chain.
Input chain length must be between 12 and 3,204 residues.
Chains longer than 3,204 residues must be split before submission using software such as Molmil or PyMOL.
CA-only chains are not supported. CA atoms must make up less than 90% of total number of atoms.
Input chain must contain usable secondary structure (as determined by ASH).

How It Works

Search by Structure uses a protein structural search index built from the comprehensive pairwise structural alignment data available in DASH. Using this search index, a query protein can be quickly matched with its closest representatives from the PDB. Final results are computed by aligning the query protein against all structural neighbors for the representatives found during the index search.

Bug Reporting & Feedback

We are always looking to improve DASH based on user feedback. Please contact us with any bug reports or feedback you may have.
