Class SiftsChainToUniprotMapping


  • public class SiftsChainToUniprotMapping
    extends java.lang.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

      • load

        public static SiftsChainToUniprotMapping load()
                                               throws java.io.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:
        java.io.IOException - If the local file could not be read and could not be downloaded
      • load

        public static SiftsChainToUniprotMapping load​(boolean useOnlyLocal)
                                               throws java.io.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:
        java.io.IOException - If the local file could not be read and could not be downloaded (including if onlyLocal is true)
