Figure 3. Visualization of 15 identical (same single-nucleotide polymorphism positions call at 24 of 24 positions) and nearly identical (23 of 24 identical positions) molecular barcodes from 42 monogenomic samples from patients in Haiti, 2006 and 2007. Each node (oval) represents an individual barcode. Samples with identical barcodes are included in the same nodes, and related barcodes (1 single-nucleotide polymorphism positions difference) are connected by lines. Gray nodes indicate that there is some point of ambiguity between barcodes, defined as either both alleles detected (N) or no data (X) at a specific position, indicating <100% confidence of a complete match between barcodes.
