What you must provide?
A PDB-format file of the protein model.
If more than 100 conformers are uploaded only the first 100 will be analyzed
If the PDB file has more than one chain only the first one will be analyzed
What you will get?
A list of the predicted 13Cα and 13Cβ chemical shifts, referenced to TMS, for each amino acid residue in the sequence, values for cysteine resiudes and for the first and last residues are excluded.
