The Genome Browser Gateway page, set up to span the central portion of chromosome 7 (chr7:45,000,000-70,000,000) in the March 2006 human assembly (NCBI36). Custom annotation tracks (Support Protocol 1) can be uploaded by clicking the “add custom tracks” button. The initial Genome Browser display may be configured by clicking the “configure tracks and display” button. The lower portion of this page (not shown) displays a description of the selected assembly, relevant links, and examples of queries that may be entered in the “position or search term” box.
