Phylogenetic tree of V3 in patient p2.

Notes:

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.

Phylogenetic trees

Link color:

Region:

Notes:

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

Region:

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

Notes:

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.

Coverage

Notes:

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.

Notes:

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.

PBMC samples available for patient p2

Sample	years on treatment	good reads	hypermutated
DNA 1	6.9	reads	reads

Notes:

Times indicate sampling times relative to start of treatment.
"Good" reads are those that map to p17gag and did not have obvious signs of hypermutation.
Hypermutated reads are those that map to p17gag and showed an excess of G-to-A mutations.
