Description of user workflow within the platform

Step	Description
Step 1: Login	The user accesses the Web interface and logs in with his account, then accesses existing datasets and images
Step 2: Upload	The user can upload a new image, which triggers the image processing pipeline (described in section “image processing”)
Step 3: Explore	Once the image is processed, it is available for viewing, exploring t panning and zooming into various regions
Step 4: Overlays	The user can choose to activate one or more “feature overlays,” that superimpose visual information on top of the WSI, e.g., highlighting automatically segmented and classified ROIs
Step 5: Annotate	The user can then create new annotations by drawing a ROI with one of several drawing tools (rectangle, ellipse, freehand, etc.)
Step 6: Search within WSI	The user can then search for similar patches within the same WSI. When a ROI is selected, the system retrieves similar patches from the same image at the same scale. The user can click on the results to navigate to the relevant section of the WSI for further inspection
Step 7: Retrieval interface	The user can also decide to click on a link to open the retrieval interface, allowing to perform a search of similar patches contained in other images. Two datasets are available in the current prototype (see section “datasets”)
Step 8: PubMed central	The user can search for similar patches contained in scientific articles and navigate to those articles by following a link
Step 9: ContextVision AB	The user can search for similar patches contained in WSIs of the same dataset and navigate to the retrieved patch in the viewer
