When SlideScope is the better fit

SlideScope is useful when ND2 is one part of a mixed lab workflow. Many labs receive CZI from Zeiss systems, ND2 from Nikon systems, SVS from pathology scanners, DICOM from imaging equipment, and TIFF exports from downstream tools. A single review layer reduces the friction of asking every collaborator to install a different viewer.
