average expression function and pct

Question

[rasing02]

Hi,

In cluster 1, for gene X, if pct 1 = 0.50 and pct 2 = 0.30, then the average expression function calculates the average based on only cells that express that gene (50% for pct1 and 30% for pct2) or account for all the cells (100%) present in the cluster.

Thank you, Best, R
