Users can enable users to explore the characteristic spatial changes in the activity of cancer-related functional states, hallmarks, and pathways in cancer tissue slices, as well as their associations with drug perturbations. Thus, it can be used to uncover cancer function features that could influence spatial drug perturbation effects, interpreting the characteristic changes of cell states at the spatial level under drug action, and providing key data support for revealing the spatial specificity mechanism of cancer drug response and optimizing therapeutic strategies.
