Table 2 Coverage (percentage of True Positives identified before the first False Positive) and the average percentage of errors per sequence at the MEP of HMM-d and HMM-ModE for classification of Level-2 sub-families of Class A and Class C GPCR proteins

From: HMM-ModE – Improved classification using profile hidden Markov models by optimising the discrimination threshold and modifying emission probabilities with negative training sequences
