Bio::Align::PairwiseStatistics(3)

NAME
Bio::Align::PairwiseStatistics - Base statistic object for Pairwise Alignments

SYNOPSIS
  use strict;
  my $stats = Bio::Align::DNAStatistics->new();

  # get alignment object of two sequences somehow
  my $pwaln;
  print $stats->number_of_comparable_bases($pwaln);

DESCRIPTION
Calculate pairwise statistics.

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

  number_of_comparable_bases
 Title   : number_of_comparable_bases
 Usage   : my $bases = $stat->number_of_comparable_bases($aln);
 Function: Returns the count of the number of bases that can be
           compared (L) in this alignment ( length - gaps)
 Returns : integer
 Args    : L<Bio::Align::AlignI>

  number_of_differences
 Title   : number_of_differences
 Usage   : my $nd = $stat->number_of_distances($aln);
 Function: Returns the number of differences between two sequences
 Returns : integer
 Args    : L<Bio::Align::AlignI>

  number_of_gaps
 Title   : number_of_gaps
 Usage   : my $nd = $stat->number_of_gaps($aln);
 Function: Returns the number of gapped positions among sequences in alignment
 Returns : integer
 Args    : L<Bio::Align::AlignI>
