A comparison of entropy profiles for each method applied to the variable V1 region (HXB2 131–157) of 156 HIV-1 subtype B sequences. a NGlyAlign + Dialign (70 residues), b HIVAlign (50 residues), c ClustalW (75 residues), d Muscle (61 residues), e T-Coffee (78 residues), f Clustal Omega (50 residues). Note: for each plot, x-axis values are corresponding alignment positions by the method and y axis values are entropies at those positions. For comparison, the N-glycans at HXB2 positions 136, 141 and 156 are included in red
