Heatmap representation of CNVs in all individuals. Columns represent individuals and rows represent a transformed measure of the posterior probability of each aCGH probe coming from a loss, normal copy, or gain state, denoted as PLoss, PNormal, and PGain, respectively. Specifically, for each probe, the posterior probabilities of each state obtained from RJaCGH were converted into a single value by first dividing all three posterior probabilities by the largest value and then calculating a transformed score defined as (PGain - PNormal) - (PLoss - PNormal), which results in a probe score that varies between -1 and 1. The values of -1, 0, and 1 correspond to the strongest evidence for loss, normal copy, and gains, respectively. Intermediate values reflect more uncertainty as to the state a given probe is in. Breeds are abbreviated as follows: Alaskan Malamute (AKM), Border Collie (BC), Beagle (BGL), Brittany (BRT), Boxer (BXR), Dachshund (DSH), Greyhound (GRY), German Shepherd (GSH), Jack Russell Terrier (JRT), Labrador Retriever (LBR), Shar Pei (SHP) and Standard Poodle (STP).
