Draw representations of organism chromosomes with added information. These classes are meant to model the drawing of pictures of chromosomes. This can be useful for lots of things, including displaying markers on a chromosome (ie. for genetic mapping) and showing syteny between two chromosomes. The structure of these classes is intended to be a Composite, so that
it will be easy to plug in and switch different parts without
breaking the general drawing capabilities of the system. The
relationship between classes is that everything derives from
_ChromosomeComponent, which specifies the overall interface. The parts
then are related so that an Organism contains Chromosomes, and these
Chromosomes contain ChromosomeSegments. This representation differents
from the canonical composite structure in that we don't really have
Most of the time the ChromosomeSegment class is what you'll want to customize for specific drawing tasks. For providing drawing capabilities, these classes use reportlab: http://www.reportlab.com This provides nice output in pdf, which it should be possible to convert to a wide variety of other formats. There is also the start of support for other formats (such as eps), but it doesn't seem to be quite working right for me yet...
