This patient was not part of the initial study because of suspected super-infection. It was hence not suitable for an analysis of diversification and reversion.

Phylogenetic tree of V3 in patient p4.

  • RNA template counts are estimated two limiting dilutions series using fragment 4
  • An orange label for a fragment indicates problematic amplification and possible loss of variation.
  • A red label indicates a missing fragment.
Link color:
  • To display a phylogenetic tree of a particular region of the genome, select it in the pull-down menu.
  • Choices ending on minor include minor haplotypes from each time point, others display only consensus sequences
  • The size of the Tip circles indicate the frequency of the corresponding haplotype.
  • HIV recombines. Hence there trees don't necessarily depict the actual evolutionary history of the chosen part of the genome.
  • These are approximate maximum-likelihood trees generated with Fasttree

Note: low diversity might be due, in addition to biological reasons, to a low RT-PCR efficiency in a specific amplicon.

  • The top panels show divergence and diversity averaged in sliding windows of ??? bases for every position of the genome at particular time point.
  • The time point can be varied by moving the slider at the bottom.
  • The graph shows coverage at every postition in the genome.
  • The red line indicates the number of amplified RNA templates estimated from two limiting dilution series.
  • The each fragment corresponds to one of the peaks in coverage. Coverage tends to be lower towards the end of the fragments.
  • Where fragments overlap, the sum of reads from both fragments is reported
  • Some fragments amplify less well than other (F5 in particular). These tend to have low coverage or are sometimes missing completely.
  • The top panel shows single nucleotide polymorphism (SNP) frequencies through time. Color indicates position along the genome.
  • The panel below shows SNP frequencies at each position for a given time point. The color of each point equals that of the corresponding trajectory in the top panel.
  • The time point shown in the second panel can be chosen via the slider on top.
  • Clicking on an annotated element of the genome will zoom into that element.
