Figure 3: PASTE Pairwise Slice Alignment of squamous cell carcinoma (SCC) [21].
(a) Percentage of aligned spots from PASTE pairwise alignments of adjacent slices that have the same published cluster label from [21]. (b) Published cluster labels of spots in slice A of patient 2 have moderate spatial coherence. (c) Stacked 3D alignment of SCC tumor from patient 2 produced by PASTE using pairwise alignments of adjacent slices. Slices are colored according to published cluster labels. (d) Published cluster labels of spots in slice A of patient 9 have lower spatial coherence. (e) Stacked 3D alignment of SCC tumor from patient 9. (f) Percentage of aligned spots with same cluster label is larger for slices with higher spatial coherence score.
