1. A computer-implemented method for determining a relationship between biomarker expression levels of morphological units in biological tissue and spatial distance from a morphological feature, the method comprising: identifying a morphological feature in an image of the biological tissue based on expression levels of a first biomarker indicative of the morphological feature; receiving a result of a segmentation analysis performed on the image of the biological tissue, the result identifying a first set of morphological units in the image external to the morphological feature, the first set of morphological units including cells and/or sub-cellular components; determining an expression level of a second biomarker corresponding to each unit in the first set of morphological units in the image of the biological tissue; determining a spatial distance between the morphological feature and each unit in the first set of morphological units; and automatically rendering, on a user interface displayed on a visual display device, a representation of a relationship between the expression levels of the second biomarker and the corresponding spatial distance from the morphological feature of the first set of morphological units.
