  1. Scenario 1 Anotation: Gene of which little is known What follows is a simulation of an orf page in the proposed graphical interface. The interface does not yet exist. As you go through the simulation please consider what capabilities you would want to serve your research and annotation interests. A narrative to help you go through the simulation appears in a red-bordered box, such as the one below. To begin:1. Click on Slide Show, (on the upper toolbar)2. Click View Show3.

  18. Scenario 1 Anotation: Gene of which little is knownSummary • The Annotation Page provides links to different views of the region surrounding the gene • The page links to other pages that facilitate downloading sequences • The page provides experimental data when available regarding the orf and its cyanobacterial orthologs • DNA features can be visualized wthin the context of the genetic neighborhood of the orf A prototype of the Annotation Page exists in CYORF, but the full capabilities described here require the resources we are asking of NSF.
