       Bio::Search::HSP::ModelHSP - A HSP object for model-based searches


           use Bio::Search::HSP::ModelHSP;
           # us it just like a Bio::Search::HSP::ModelHSP object


       This object is a specialization of Bio::Search::HSP::ModelHSP and is used for searches
       which involve a query model, such as a Hidden Markov Model (HMM), covariance model (CM),
       descriptor, or anything else besides a sequence. Note that results from any HSPI class
       methods which rely on the query being a sequence are unreliable and have thus been
       overridden with warnings indicating they have not been implemented at this time.


   Mailing Lists
       User feedback is an integral part of the evolution of this and other Bioperl modules. Send
       your comments and suggestions preferably to the Bioperl mailing list.  Your participation
       is much appreciated.
                  - General discussion  - About the mailing lists

       Please direct usage questions or support issues to the mailing list:

       rather than to the module maintainer directly. Many experienced and reponsive experts will
       be able look at the problem and quickly address it. Please include a thorough description
       of the problem with code and data examples if at all possible.

   Bio::Search::HSP::HSPI methods
       Implementation of Bio::Search::HSP::HSPI methods follow

        Args    : 'hit' or 'subject' or 'sbjct' to retrieve the strand of the subject.
                  There is no strand available for 'query', as the query is a model
                  and not a true sequence.

        Argument  : seq_type = 'query' or 'hit' or 'sbjct' (default = 'sbjct').
                  :  ('sbjct' is synonymous with 'hit')
                  : default is 'sbjct'
                  : Note: if there is no sequence available (eg for a model-based
                  : search), this returns a LocatableSeq object w/o a sequence
        Throws    : Propagates any exception that occurs during construction
                  : of the object.
        Comments  : The sequence is returned in an array of strings corresponding
                  : to the strings in the original format of the Blast alignment.
                  : (i.e., same spacing).

                   this may be greater than either hit or query )
        Returns  : integer

ModelHSP methods overridden in ModelHSP

       The following methods have been overridden due to their current reliance on sequence-based
       queries. They may be implemented in future versions of this class.
