"WebbA shared Nearest Neighbor (SNN) Graph was then constructed to identify clusters on the low-dimensional space, using the top 30 statistically significant principal components (PCs). Transcriptomic profiles of the resulting clusters were then individually examined to define cell types based on well-established cell marker genes (STable 2). " - Shared nearest neighbor snn graph
