fold change(差異倍數), P-value(差異的顯著性)

log test exp res val count adjust 數值 gen

fold change的意思是樣本質檢表達量的差異倍數,log2 fold change的意思是取log2,這樣可以可以讓差異特別大的和差異比較小的數值縮小之間的差距。
Q-value,是P-value校正值,P值是統計差異的顯著性的。Q值比P值更嚴格的一種統計。

The mean UMI counts per cell of this gene in cluster i
The log2 fold-change of this gene‘s expression in cluster i relative to other clusters
The p-value denoting significance of this gene‘s expression in cluster i relative to other clusters, adjusted to account for the number of hypotheses (i.e. genes) being tested.
