GEB displays for tiling microarray data. (A) Physical map display of demonstration tiling array data for a ~160 kb region on mouse chromosome 18 covering the Commd10 gene. Each colour-coded glyph corresponds to one tiling probe in the region, where the colour reflects enrichment (red), depletion (blue) or no change (black) of signal relative to the control. Closely-packed glyphs may generate blocks of red, blue or black, allowing users to quickly scan across a region for specific patterns. As for expression array data display, the enrichment/depletion thresholds can be adjusted in real-time using the sliding bars on the left, and the colours of the glyphs will change accordingly. Additionally, the maximum scale ("Max scale") for the y-axis of the graph can also be adjusted in real-time. (B) A 14 kb physical map zoomed in from Figure 4A, showing the first four exons of the Commd10 gene. As the glyphs (probes) and the graph are less condensed, the peaks and troughs of the graph can be seen clearly, allowing users to study local patterns in detail.
