Hi -
 
In biojava Annotations have no location. They are global to the Annotatable object. 
They can be localized to a region by being applied to a Feature. So to generate a 
track of "annotations" you would instead create a track of annotated Features.

        Subject: [Biojava-l] Best way to represent multiple annotation "tracks"
        
        

        Hi folks,
        
        I'm working on a gene expression data visualization program --
        
           http://genetics.stanford.edu/~ihab/caryoscope/
        
        I have not used BioJava yet for the data model, but I would like to
        migrate in that direction. It seems that my data model is very
        similar to BioJava's, except for one thing that puzzles me: How would
        you folks represent multiple "tracks" of annotation values? The way I
        have things modeled --
        
        
        
http://genetics.stanford.edu/~ihab/caryoscope/doc/api/edu/stanford/genomics/domain/Dataset.html
        
        a Dataset object maps a Feature to a data object (or null). I see you
        folks implement this a bit differently: a Feature implements
        interface Annotatable, whereby it becomes responsible for knowing
        about its own Annotations. Hence my question -- how would you
        represent a "track" of annotations as a single entity?
        
        Thanks a lot for any help you can provide in pointing me in the right
        direction. Peace,
        
        Ihab
