Figure 3

Genotype and CN state visualisation. The portions of chromosome 14 and 15 of 10 subjects numbered 1 – 10, are shown. A) Genotype and CN state visualisation mode. As seen better in the magnified portion, the colour of the squares depends on the SNP genotype, whereas their height is proportional to their CN states. A deletion and a duplication are shown by arrows. B) "Show genomic variation only" visualisation mode. When this option (shown by a red rectangle at the bottom of the page) is selected, all SNPs with a CN state equal to state 2 are turned into white to improve the visualisation of deletions and duplications only. To show the chromosomal position of one of the visualised duplications, the information about the position of the first and last duplicated probes is reported. This information is usually displayed at the bottom of the window by clicking on the region of interest.
