Figure 5.
Tissue × Stage Matrix. The view displays a set of expression data (in this case expression data for genes associated with the phenotype ‘embryonic lethality’) in a grid comprised of rows of anatomical structures and columns of Theiler stages. (a) The anatomy has toggles (small blue triangles) that can be opened and closed to expand the anatomy to more granular structures (red arrow follows the path from ‘germ layer’ to ‘yolk sac endoderm’). (b) The Matrix Legend details the meanings for the colors and other symbols, such as the red corner that indicates conflicting results (both present and absent) in the structure at that stage, and the small gray circle indicating a tissue exists at the stage, but no annotations are available. (c) When no ‘present’ annotations exist for a term, the matrix displays gold triangles to point users to ‘absent’ annotations in substructures (black bracket). (d) Clicking an individual cell opens a dialog box detailing the results associated with that tissue/stage combination. Users have the option to view the results or associated images in more detail.
