Notice samples suspected of Mycoplasma Contamination (upper figure, Figure 5) are correlated but the rest of GEO is not (lower figure, Figure 6).
Click on images for details of Figures 5 and 6 in
technical report RN/12/11.
Once there click above diagonal for individual scatter plots
and below diagonal to jump into dynamic RNAnet scatter plot
with links to metadata in
NCBI gene expression omnibus (GEO)
for each data point.
After loading RNAnet scatter plots remember to press plot. Drag blue cross hair to data points of interest then click hyperlinks to access GEO description of experiment (which may include publication details).
