CNViewer
CNViewer shows CNV and LOH data in affected and unaffected individuals
...As well as visualising the CN state and LOH data, the program will also display Log(2) ratio, smooth signal and allele difference values that may also be obtained from the Affymetrix SNP 6.0 array (details on how to export the data are here). CN state, Log(2) ratio and the smooth signal data may be derived from either the SNP or CNV probes on the SNP microarray chip, where as the LOH and allele difference values are derived solely from the SNP probes.
