Fig. 4From: Genome-wide discovery of lincRNAs with spatiotemporal expression patterns in the skin of goat during the cashmere growth cycleHierarchical clustering of all differentially expressed genes (a) and lincRNAs (b). We transformed the RPKM values into the log10 (FPKM+ 1) values and then calculated the Z-score for every log10 (FPKM+ 1) value within each tissue. The five main clusters (K1-K5) are presented on the left panel aBack to article page
