Example of a simple sample switch.

<p>One expression BeadChip (12 arrays), and two plates of samples for genotyping are illustrated. In particular, in the left panel, the intended locations of two samples are highlighted (in blue and red) for the two technologies. The BADGER ranks for the association between these two expression arrays and genotype arrays are high and indicate that there is a mis-mapping. On the right hand side the resolution to this example is shown. Not only with a simple switch can we match the expression arrays to the genotype arrays (now with BADGER ranks of 1), but since the two genotyping arrays are from different plates, while the two expression arrays are neighbouring, we can deduce that the error took place on the expression chip.
