Extended Data Fig. 3: Segmentation examples of C. reinhardtii lamellae medium magnification montages.

Shown are 3 examples of medium magnification montages of lamellae milled from C. reinhardtii cells (left) and their segmentations using the SPACEtomo model trained on S. cerevisiae (right). While some classes (for example ice contamination, dark and bright areas, coating) are successfully segmented by the Yeast model, cellular classes are principally misclassified.
