Figure 7From: Prediction of regulatory elements in mammalian genomes using chromatin signaturesThe HMM Classifier. (a) A left-right HMM with Q states. Each state has a transition to itself and outgoing transitions toward higher states behind. Once a state is left it never comes back in a left-right model. (b) Three HMMs are trained separately for promoter, enhancer and background. Log-odds are calculated to classify a genomic region (see Methods).Back to article page
