Polymers and bracket components - search options

    In this document the search options concerning polymers and bracket components are summarized and their usage is shown in different search interfaces.

    Copolymer matching

    Adjusts copolymer matching mode. If y(yes)/true then target polymers in copolymers can only be matched by query polymers in copolymers. Default value is n (no)/false. MolSearch API

    
        MolSearchOptions searchOptions = new MolSearchOptions(SearchConstants.SUBSTRUCTURE);
        searchOptions.setCopolymerMatching( true / false );
        // ...
        MolSearch searcher = new MolSearch();
        searcher.setSearchOptions(searchOptions);

    JChemSearch API

    
        JChemSearchOptions searchOptions = new JChemSearchOptions(SearchConstants.SUBSTRUCTURE);
        searchOptions.setCopolymerMatching( true / false );
        // ...
        JChemSearch searcher = new JChemSearch();
        searcher.setSearchOptions(searchOptions);

        JChemSearch searcher = new JChemSearch();
        searcher.setSearchOptions(searchOptions);

Default value is true

Use the jc_compare operator with mix:d/i,
which specifies whether COM, MIX and FOR sgroups should be considered during search.

    d (default): do consider;
    i: ignore.

Example: SELECT count(*) FROM nci_150k WHERE jc_compare(structure, 'Brc1ccccc1', 't:s mix:i') = 1;

    jcsearch command line tool

    
Use the following command line parameter:

--mix:d/i , where

    d: default;
    i: ignore brackets.

    Ignore polymer brackets

    Adjusts polymer matching. True - if polymer sgroups should be considered during search. Default value is true. MolSearch API

    
        MolSearchOptions searchOptions = new MolSearchOptions(SearchConstants.SUBSTRUCTURE);
        searchOptions.setPolymerMatching( true / false );
        // ...
        MolSearch searcher = new MolSearch();
        searcher.setSearchOptions(searchOptions);

    JChemSearch API

    
        JChemSearchOptions searchOptions = new JChemSearchOptions(SearchConstants.SUBSTRUCTURE);
        searchOptions.setPolymerMatching( true / false );
        // ...
        JChemSearch searcher = new JChemSearch();
        searcher.setSearchOptions(searchOptions);

    JChem Oracle Cartridge

    
Use the jc_compare operator with polymer:d/i.

    d (default): do consider;
    i: ignore polymer brackets.

    jcsearch command line tool

    
Use the following command line parameter:

--polymer:d/i, where

    d: default;
    i: ignore brackets.

    Polymer end group matching

    Adjusts polymer end group matching. True - if polymer end groups should be matched during search. In this case the star atom can't match on a specified end group.

    Default value is true. See examples here. MolSearch API

    
        MolSearchOptions searchOptions = new MolSearchOptions(SearchConstants.SUBSTRUCTURE);
        searchOptions.setEndgroupMatching( true / false );
        // ...
        MolSearch searcher = new MolSearch();
        searcher.setSearchOptions(searchOptions);

    JChemSearch API

    
        JChemSearchOptions searchOptions = new JChemSearchOptions(SearchConstants.SUBSTRUCTURE);
        searchOptions.setEndgroupMatching( true / false );
        // ...
        JChemSearch searcher = new JChemSearch();
        searcher.setSearchOptions(searchOptions);

    JChem Oracle Cartridge

    
Use the jc_compare operator with endGroupMatching:y/n.

    yes (default);
    n: no.

--endGroupMatching:y/n

    y: yes (default);
    n: no

    Polymer phase-shift

    Adjusts if the phase shifted polymer should match on the original. True if the phase shifted should be matching; false otherwise. Default value is true. See examples here. MolSearch API

    
        MolSearchOptions searchOptions = new MolSearchOptions(SearchConstants.SUBSTRUCTURE);
        searchOptions.setPhaseShiftedMatching( true / false );
