WebAfter identification of the cell type identities of the scRNA-seq clusters, we often would like to perform differential expression analysis between conditions within particular cell types. While functions exist within Seurat to perform this analysis, the p-values from these analyses are often inflated as each cell is treated as a sample. Weba function to calculate average expression (mean.function) and dispersion (dispersion.function) for each gene. Next, divides genes into num.bin (deafult 20) bins based on their average expression, and calculates z-scores for dispersion within each bin. The purpose of this is to identify variable genes while controlling for
