Class SiftsChainToUniprotMapping

java.lang.Object

org.biojava.nbio.structure.io.sifts.SiftsChainToUniprotMapping

public class SiftsChainToUniprotMapping
extends Object

A mapping between UniProt entries and PDB chains. For example

 SiftsChainToUniprot sifts = SiftsChainToUniprot.load();
 SiftsChainEntry entry1 = sifts.getByUniProtId("P04585");
 System.out.println(entry1.getPdbId() + "." + entry1.getChainId()); // 1hiv.A
 System.out.println(entry1.getPdbStart() + "-" + entry1.getPdbStop()); // 1-99
 SiftsChainEntry entry2 = sifts.getByChainId("1hiv", "A");
 System.out.println(entry1.equals(entry2)); // true

Method Detail

load

public static SiftsChainToUniprotMapping load()
                                       throws IOException

Loads the SIFTS mapping. Attempts to load the mapping file in the PDB cache directory. If the file does not exist or could not be parsed, downloads and stores a GZ-compressed file.

Returns:

Throws:

IOException - If the local file could not be read and could not be downloaded

load

public static SiftsChainToUniprotMapping load(boolean useOnlyLocal)
                                       throws IOException

Loads the SIFTS mapping. Attempts to load the mapping file in the PDB cache directory. If the file does not exist or could not be parsed, downloads and stores a GZ-compressed file.

Parameters:

useOnlyLocal - If true, will throw an IOException if the file needs to be downloaded

Returns:

Throws:

IOException - If the local file could not be read and could not be downloaded (including if onlyLocal is true)
