I am analysing RNA-Seq data from the Human Developmental Transcriptome dataset. I have seen that the RNA-Seq data was obtained from 42 brain samples from donors of different ages, and that there are 524 anatomically annotated samples in total.
I am making heatmaps using the RNA-Seq data to show the expression of some genes of interest in specific brain regions. I want to standardise the the RPKM values using a Z-score transformation. However, I have read that the Z-score transformation can only be applied for values that are obtained within a single experiment.
Would it be possible to know if the RPKM values for all genes in all the brain samples in the dataset were obtained in a single RNA-Seq experiment?
