Screenshot of GATMD advanced search functions. The general data categories of GATMD are shown on the left (see also Table 1). Selecting from this list will display the relevant data sub-categories (i.e. formal parameters) on the right. Selecting any formal parameter displays a brief description, the type of data it contains, appropriate values that may be passed to it for searching the database, as well as a query example. Advanced queries must conform to the guidelines outlined in text and described in greater detail in the online tutorial.
