Genes by counts

WebJun 16, 2024 · For genes with lower counts, however, the values are shrunken towards the genes’ averages across all samples. Using an empirical Bayesian prior on inter-sample differences in the form of a ridge penalty , the rlog-transformed data then becomes approximately homoskedastic , and can be used directly for computing distances … WebIf a gene is only expressed in a handful of cells, it is not particularly meaningful as it still brings down the averages for all other cells it is not expressed in. For our data we choose to keep only genes which are expressed in 10 or more cells. By using this filter, genes which have zero counts in all cells will effectively be removed.
