      Returns hits as result of r-group decomposition according to the original query. Various results are returned in one RgDecompResults object: More details about r-group decomposition can be found here. For more sophisticated usages (e.g. all hits of query in a specific target) see our RGroupDecomposition API documentation.
      Parameters:
      hits - cd_ids of target structures
      attachmentType - Type of visualization of attachment of ligands.
      Returns:
      An RGDecompResults object.
      Throws:
      SQLException - if an sql exception is encountered
      SearchException - Search failure
      MolFormatException - if the molecule can't be read

    • getHitsAsMolecules

      public Molecule[] getHitsAsMolecules(int[] idList, HitColoringAndAlignmentOptions options, List<String> dataFieldNames, List<Object[]> dataFieldValues) throws SQLException, IOException, SearchException, DatabaseSearchException
      Returns hits ready for display. If hit alignment or coloring is needed, the graph search must be repeated for the selected structures to obtain the atom indexes of hits. (Storing this data would consume too much memory for large hit sets) If alignment mode has been set to rotate, and query has 0 dimension, it will be cleaned in 2d. If alignment mode has been set to partial clean, this option will be changed to rotate in this case.
      Parameters:
      idList - the cd_id list of hits to be retrieved.
      options - the options for coloring and alignment. If null the structures will be displayed in their original form.
      dataFieldNames - fields of the jchem table that should be fetched together with the structure or null.
      dataFieldValues - an empty List required or it can be null. The fetched values will be stored in this object as Object[] elements.
      Returns:
      the hits as Molecules, colored and aligned if needed. If coloring is specified in case of SearchConstants.SUPERSTRUCTURE search mode, always the query structure is returned, the target subgraph is colored. If there is no hit for a target then the appropriate element of the result array is null.
      Throws:
      SQLException - if the fetched row is deleted
      IOException - if an io error is encountered
      SearchException - if an error occurred during search
      DatabaseSearchException - if an error occurred during search

    • getHitsAsHitDisplayTool

      public HitDisplayTool getHitsAsHitDisplayTool(int[] idList, HitColoringAndAlignmentOptions options, List<String> dataFieldNames, List<Object[]> dataFieldValues, List<? super Molecule> molecules, List<byte[]> sources) throws SQLException, IOException, SearchException, DatabaseSearchException
      Gets a HitDisplayTool object from which the results can be retrieved. Parameters are similar to getHitsAsMolecules(int[], HitColoringAndAlignmentOptions, List, List) Additional parameters: molecules, sources Example usage: 
       List<Molecule> molecules = new ArrayList<Molecule>();
 List<byte[]> sources = new ArrayList<byte[]>();
 HitDisplayTool colorUtil = getHitsAsHitDisplayTool(idList, options,
         dataFieldNames, dataFieldValues, molecules, sources);
 for (int x = 0, n = molecules.size(); x < n; x++) {
     if (molecules.get(x) == null) { // not found
         continue;
     }
     colorUtil.setMoleculeMarkushSourceTarget(molecules.get(x), sources.get(x));
     // fetch the hits using colorUtil.getNextHit() or colorUtil.getHits(int)
     // ...
 }
      Parameters:
      idList - the cd_id list of hits to be retrieved.
      options - the options for coloring and alignment. If null the structures will be displayed in their original form.
      dataFieldNames - fields of the jchem table that should be fetched together with the structure or null.
      dataFieldValues - an empty List required or it can be null. The fetched values will be stored in this object as Object[] elements.
      molecules - An empty list that will contain the molecules to be set on the hitdisplaytool object. For not found IDs (e.g. deleted) null is set.
      sources - An empty list that will contain the byte array sources to be set on the hitdisplaytool object.
      Returns:
      the hitDisplayTool object
      Throws:
      SQLException - if an sql error encountered
      IOException - if an io exception is encountered
      SearchException - if an error occurred during search
      DatabaseSearchException - if an error occurred during search
