Figure 2From: Accurate and efficient gp120 V3 loop structure based models for the determination of HIV-1 co-receptor usageV3 loop sequence logos for the 989 R5 and 204 DM dataset variants. The size of the letters at each position is indicative of their relative frequencies of occurrence among the sequences in the co-receptor class. The red arrows identify the top ten positions in the variant residual profile vectors for predicting co-receptor phenotype, ranked by an SVM classifier and a 10-fold CV attribute selection mode.Back to article page
