48 RELAX is a hypothesis testing framework that asks whether the strength of natural selection has been relaxed or intensified along a specified set of test branches. RELAX is therefore not a suitable method for explicitly testing for positive selection. Instead, RELAX is most useful for identifying trends and/or shifts in the stringency of natural selection on a given gene. 48 RELAX: a test for selection differences
49 =======================================
49 50
50 See the online documentation_ for more information. 51 What question does this method answer?
52 --------------------------------------
51 53
52 .. _documentation: http://hyphy.org/methods/selection-methods/#relax 54 Is there ev- idence the strength of selection has been relaxed (or conversely intensified) on a specified group of lineages (TEST)
55 relative to a set of reference lineages (RELAX)? Importantly, RELAX is not designed to detect diversifying selection specifically.
56 We note that the RELAX framework can perform both this specific hypothesis test as well as fit a suite of descriptive models which address,
57 or example, overall rate differences between test and reference branches or lineage-specific inferences of selection relaxation.
58
59 Recommended Applications
60 ------------------------
61
62 1. Testing for a systematic shift (relaxation / intensification) in the distribution of selection pressure associated with major biological transitions such as hosting switching in viruses, lifestyle evolution in bacteria (i.e. transition from free-living to endosymbiotic lifestyle
63 2. Comparing selective regimes between two subsets of branches in the tree, e.g. to investigate selective differences due an environmental/phenotypic changes.

65
66 Brief description
67 -----------------
68
69 RELAX (a random effects test of selection relaxation) uses a random
70 effects branch-site model framework to test whether a set of 'Test'
71 branches evolves under relaxed selection relative to a set of
72 'Reference' branches (R), as measured by the relaxation parameter (K).
73
74 Input
75 -----
76
77 1. A *FASTA* sequence alignment.
78 2. A phylogenetic tree in the *Newick* format that is further partitioned into one or two groups (_TEST_ or _TEST_ and _REFERENCE_). See http://hyphy.org/tutorials/phylotree/
79
80 Note: the names of sequences in the alignment must match the names of the sequences in the tree.
81
82
83 Output
84 ------
85
86 A JSON file with analysis results (http://hyphy.org/resources/json-fields.pdf).
87
88 A custom visualization module for viewing these results is available (see http://vision.hyphy.org/RELAX for an example)
