用x 表示领域大小 (neighborhood size，例如对5,000细胞的数据，pK=0.01时，相当于寻找给定细胞近邻的200个细胞)。将人造NN (artificial nearest neighbors，ANN) 数除以领域大小，得到人造NN的比例 ( panw =n(模拟的doublets)/n(真实细胞+模拟的doublets)) ;
这里通过pk=0.01算出来200个细胞是怎么算的？
For example, in a dataset with 15,000 real cells, a pN of 0.25 would represent the integration of 5,000 artificial doublets, and a pK of 0.01 would represent a pK of 200 cells.
