Difference of CN probes and SNP probes on genotyping microchip arrays
... Is there a difference between copy number (CN) probes compared to SNP probes on SNP arrays such as the Affymetrix 6.0 SNP array? Physically there could be longer oligos for the CN probes? Do you have to analyse both probes differently, e.g. do tools such as PennCNV use both probes for CNV detectio ...

Comment: C: CNV analysis for targeted genomic region
... You could try to calculate the coverage per gene/exon/target, median normalize over all/within sets, build a reference sample supposed to be copy number of two, calculate the ratio between target and reference sample and perform a cluster analysis for CNV detection per gene/exon/target. This is simi ...
