NAME

Bio::Tools::BPlite::Sbjct - A Blast Subject (database search Hit)

SYNOPSIS

   use Bio::Tools::BPlite;
   my $report = new Bio::Tools::BPlite(-fh=>\*STDIN);
   while(my $sbjct = $report->nextSbjct) {
       $sbjct->name;    # access to the hit name
       "$sbjct";        # overloaded to return name
       $sbjct->nextHSP; # gets the next HSP from the sbjct
       while (my $hsp = $sbjct->nextHSP) {
          # canonical form is again a while loop
       }
   }
 
 

DESCRIPTION

See Bio::Tools::BPlite for a more detailed information about the BPlite BLAST parsing objects.

The original BPlite.pm module has been written by Ian Korf! See http://sapiens.wustl.edu/~ikorf

The Sbjct object encapsulates a Hit in a Blast database search. The Subjects are the ``Hits'' for a particular query. A Subject may be made up of multiple High Scoring Pairs (HSP) which are accessed through the nextHSP method.

If you are searching for the P-value or percent identity that is specific to each HSP and you will need to use the nextHSP method to get access to that data.

APPENDIX

The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _

name

  Title    : name
  Usage    : $name = $obj->name();
  Function : returns the name of the Sbjct 
  Example  : 
  Returns  : name of the Sbjct 
  Args     :
 
 

report_type

  Title    : report_type
  Usage    : $type = $sbjct->report_type()
  Function : Returns the type of report from which this hit was obtained.
             This usually pertains only to BLAST and friends reports, for which
             the report type denotes what type of sequence was aligned against
             what (BLASTN: dna-dna, BLASTP prt-prt, BLASTX translated dna-prt, 
             TBLASTN prt-translated dna, TBLASTX translated dna-translated dna).
  Example  : 
  Returns  : A string (BLASTN, BLASTP, BLASTX, TBLASTN, TBLASTX, UNKNOWN)
  Args     : a string on set (you should know what you are doing)
 
 

nextFeaturePair

  Title    : nextFeaturePair
  Usage    : $name = $obj->nextFeaturePair();
  Function : same as the nextHSP function 
  Example  : 
  Returns  : next FeaturePair 
  Args     :
 
 

nextHSP

  Title    : nextHSP
  Usage    : $hsp = $obj->nextHSP();
  Function : returns the next available High Scoring Pair
  Example  : 
  Returns  : Bio::Tools::HSP  or null if finished
  Args     :
 
 

_readline

  Title   : _readline
  Usage   : $obj->_readline
  Function: Reads a line of input.
 
            Note that this method implicitely uses the value of $/ that is
            in effect when called.
 
            Note also that the current implementation does not handle pushed
            back input correctly unless the pushed back input ends with the
            value of $/.
  Example :
  Returns :
 
 

_pushback

  Title   : _pushback
  Usage   : $obj->_pushback($newvalue)
  Function: puts a line previously read with _readline back into a buffer
  Example :
  Returns :
  Args    : newvalue
