SYNOPSIS

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

DESCRIPTION

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.
