data-providing web service via a URL and some GET parameters in its
own non-standard format. The data-providing service must return AnnoJ-
readable objects and meta-data in JSON for AnnoJ to render (Figure 11.3).
Feature rendering is fast for gene models but somewhat slower for track
types like the histograms that show the coverage of aligned reads over
Connectivity between web browsers, web service
genome browsers and web services hosting genomic
data. A user client (web browser) makes a GET request
from a URL with certain parameters to, for example,
the AnnoJ web service (
www.annoj.org
), which returns
a Javascript library. This then requests genomics data
from the web service that hosts the genomics data
(e.g. that served by a Gee Fu instance). AnnoJ can
render and allow interactions with the genomics data
in the web browser
