Database query. Each panel corresponds to one individual webpage. (A) the introduction screen with (1) a search window, (2) general information about the database, (3) recently added species, (4) published genes and (5) laboratories that have contributed gene expression patterns. At this point the user can search a gene expression pattern by entering a single gene name and query in one or all available species simultaneously. (B) the advanced search feature for all species (default setting), where the user can search a gene expression pattern by (i) gene name, (ii) developmental stage and/or (iii) expression domain(s). Note that in this case only parent stages (for example gastrula) or parent expression domains (for example ectoderm) are shown for the sake of comparison. If one specific species is selected all sub-stages (for example mid-gastrula) and all sub-domains (for example pharyngeal ectoderm) are shown and can be used for the advanced search (more details about the advance search are shown in Figure 5).
