Figure 2From: RAIphy: Phylogenetic classification of metagenomics samples using iterative refinement of relative abundance index profilesClassification accuracy for different distance metrics. The accuracy performance of different distance/similarity metrics for 28 taxa with varying fragment lengths is shown. The frequencies of 7-mers were used. Using the metric defined by Sandberg et al. appears to be more accurate for all fragment lengths than employing Euclidean distance and Pearson correlation coefficients.Back to article page
