The graphical navigation element of the EPD. (A) The search mode display bar has two values; either protein analysis mode, or global analysis mode. The former filters out datasets that have not detected the selected protein, the latter allows access to all public datasets (and private ones if the user has the appropriate credentials). (B) The icons section: displays on the far right include a button with a link to the EPD’s twitter page, the middle button opens an information pop-up about the EPD and the left button a tooltip control. The tooltips can but toggled on/off by clicking on this button (represented by a white check inside a green circle). It is enabled on desktops and disabled on mobile/tablets by default. (C) The EPD search box: This input box is used to search for datasets containing a specific protein of interest. The search can be performed by typing either the gene name, protein description, protein name, or protein accession. It is automatically updated to search for protein association in the current hierarchy. (D) Information button: These two buttons are only visible for the protein analysis mode. They display additional information and external links for the selected protein. (E) The tool tip: This element is only visible if it has both been enabled (see B above) and the cursor is above a node in the force diagram. It provides a longer description of the element that is currently being hovered over. (F) The force diagram: This is the interactive graphical navigation element. It displays the current element in the hierarchy and allows the user to click on nodes to advance to the child nodes.
