Comparison of Affymetrix call with MPSS detection. A rank-order plot of Affymetrix ProbeSet detection calls correlated with MPSS tpm for each GeneID is shown. The MPSS tpm associated with GeneID determined to be present (black) or absent (gray) were sorted by rank order, and then one thousand values were plotted, representing the 1/1000th quantiles. Very few genes predicted to be absent by Affymetrix have a large MPSS tpm; a number of genes predicted to be present by Affymetrix have a low MPSS tpm.
