Figure 2From: Identification and correction of previously unreported spatial phenomena using raw Illumina BeadArray dataThe relationship between the fractional part of bead position and observed intensity. (A) To investigate the association between bead-intensity and the fractional part of a bead's location we use the bead coordinates and intensities for array section 4343238066_A_1. A pixel is divided into 100 × 100 bins and the average log-intensity of beads with fractional coordinates falling into those bins has been plotted. (B) As for part A of the figure, but the fractional part of the coordinate was not used in the intensity calculation, with the four pixels instead being given equal weight. (C) As for part A of the figure, but within bead-type residual log-intensities are plotted. (D) As for part B of the figure, but within bead-type residual log-intensities are plotted.Back to article page
