PROSPECT uses templates to predict the protein structure, i.e., 1qhaa, 1erja, 1b4ka, etc, what do these terms mean?
Those template names are the PDB ids for the specific proteins. Each structure in the PDB is represented by a 4 character alphanumeric identifier, assigned upon its deposition. For example, 4hhb and 9ins are identification codes for PDB entries for hemoglobin and insulin, respectively. Many of the PDB Web site pages, including the PDB home page, allow you to enter a PDB ID and retrieve information for the corresponding structure. PDB’s page is at: http://www.rcsb.org/pdb/index.html The last letters of the longer IDs (as those mentioned have more than 4 characters) are the chain identifiers for proteins consisting of multiple polypeptide chains.
