exMatch is a tool where the user can find genes by colouring samples. There is a colour legend on the left side of the tool and user needs to drag desired colours from the colour palette and drop into the relevant sample image. Once the user clicks “Find Genes” button, the tool will find corresponding genes based on shaded samples. The underlying principle is the opposite to the functionalities of the exImage tool. Currently, this brand new tool only exists in the EucGenIE.org web resource
