A computer-implemented method for displaying expression levels of one or more biomarkers in a field of view, the field of view corresponding to an image, or a portion of an image, of a biological specimen, the method comprising: rendering a graphical user interface on a visual display device, wherein the graphical user interface is rendered on a computing device, rendering a main image panel and a biomarker panel comprised by the graphical user interface comprising; receiving user input, selecting a field of view corresponding to a selected biological specimen; rendering, on the main image panel, a first image of the selected field of view corresponding to the biological specimen, wherein the first image comprises a tiled multi-resolution data structure having a plurality of images in an order of increasing resolution corresponding to different resolutions of the same channel of image data; rendering, overlaid on the first image in the main image panel, an interest region selection component enabling a user to select a first region within the first image, wherein the rendering comprises determining tiles of data on the expression levels of the biomarkers that are selectively required for the first region, requesting and receiving the selectively required tiles from a server; rendering, on the biomarker panel, a first set of thumbnail images corresponding to the selectively required tiles of data and the first region in the first image, the first set of thumbnail images representing expression levels of a set of biomarkers; receiving user input, on the interest region selection component rendered on the main image panel, the interest region selection component selecting a second region in the first image; and based on the user input selecting the second region in the first image, updating the biomarker panel to replace the first set of thumbnail images with a second set of thumbnail images that represents the second region of the first image that is selected by the interest region selection component corresponding to the second region in the first image and representing expression levels of the set of biomarkers, wherein the updating the biomarker panel comprises determining tiles of data on the expression levels of the biomarkers that are selectively required for the second region, requesting and receiving the selectively required tiles from the server, and rendering the selectively required tiles as the second set of thumbnail images. rendering a graphical user interface on a visual display device, wherein the graphical user interface is rendered on a computing device, rendering a main image panel and a biomarker panel comprised by the graphical user interface comprising; receiving user input, selecting a field of view corresponding to a selected biological specimen; rendering, on the main image panel, a first image of the selected field of view corresponding to the biological specimen, wherein the first image comprises a tiled multi-resolution data structure having a plurality of images in an order of increasing resolution corresponding to different resolutions of the same channel of image data; rendering, overlaid on the first image in the main image panel, an interest region selection component enabling a user to select a first region within the first image, wherein the rendering comprises determining tiles of data on the expression levels of the biomarkers that are selectively required for the first region, requesting and receiving the selectively required tiles from a server; rendering, on the biomarker panel, a first set of thumbnail images corresponding to the selectively required tiles of data and the first region in the first image, the first set of thumbnail images representing expression levels of a set of biomarkers; receiving user input, on the interest region selection component rendered on the main image panel, the interest region selection component selecting a second region in the first image; and based on the user input selecting the second region in the first image, updating the biomarker panel to replace the first set of thumbnail images with a second set of thumbnail images that represents the second region of the first image that is selected by the interest region selection component corresponding to the second region in the first image and representing expression levels of the set of biomarkers, wherein the updating the biomarker panel comprises determining tiles of data on the expression levels of the biomarkers that are selectively required for the second region, requesting and receiving the selectively required tiles from the server, and rendering the selectively required tiles as the second set of thumbnail images.
