Low correlation between processed samples of UMB1796. Frozen and fixed samples taken from case UMB1796 were processed by both IVT- and DASL-based methods. Genome-wide results are plotted to compare correlations and distributions. Scatterplots of UMB1796 replicates, histogram of data distribution, correlation, and number of up- and downregulated genes differing between samples show low correlations between brain tissue profiled using IVT- and DASL-based approaches from the same case in all except DASL technical replicates. Labels indicate assay type (DASL/IVT), preservation method (Frozen/Fixed), sample code, and replicate number (if applicable).
