Bio::Graphics::Glyph::phylo_align(3) The phylogenetic alignment glyph


See L<Bio::Graphics::Panel> and L<Bio::Graphics::Glyph>.


This glyph draws a cladogram for any set of species along with their alignment data in relation to the reference species. At high magnification, base pair alignements will be displayed. At lower magnification, a conservation score plot will be drawn. Gaps as specified by CIGAR are supported. Currently the scores are drawn to a log plot with the restriction that the score will be the same across all base pairs within an alignment. It is hoped that this restriction can be addressed in the future.

For this glyph to work, the feature must return a DNA sequence string in response to the dna() method. Also, a valid tree file must be available in a format readable by the Bio::Tree library.


The following options are standard among all Glyphs. See Bio::Graphics::Glyph for a full explanation.

  Option      Description                      Default
  ------      -----------                      -------
  -fgcolor      Foreground color               black
  -outlinecolor Synonym for -fgcolor
  -bgcolor      Background color               turquoise
  -fillcolor    Synonym for -bgcolor
  -linewidth    Line width                     1
  -height       Height of glyph                10
  -font         Glyph font                     gdSmallFont
  -connector    Connector type                 0 (false)
                Connector color                black
  -label        Whether to draw a label        0 (false)
  -description  Whether to draw a description  0 (false)
  -hilite       Highlight color                undef (no color)

In addition to the common options, the following glyph-specific options are recognized:

              mode in units of font height
              Spacing of spcies in        5
              conservation view in units
              of font height
  -hide_label Whether to label spcies     0
