Web23 Sep 2024 · The Median Gene Expression within each Cell Type (MGECT) was calculated for every gene. To remove possible housekeeping genes, genes with zero variance for their MGECT across all cell types were excluded, resulting in 13,945 genes x 15,603 samples. WebHere overdispersion of a gene set signifies that the amount of variance explained by PC1 computed for a dataset restricted to the genes from the set is significantly larger than for a random gene set of the same size. Coordinated gene set means that the spectral gap between the first and the second eigenvalues of the co-variance matrix computed ...
