FADE : FUBAR Approach to Directional Evolution
==============================================

What question does this method answer?
--------------------------------------

Which site(s) in an alignment evolve towards to or away from a particular residue.

Recommended Applications
------------------------

Screen protein sequence alignments where the direction of evolution can be resolved
(via tree rooting, e.g. using an outgroup) to find sites which evolve differently from
a standard protein model (selected by the user), or a gene-average model (GTR) to find
evidence of directional selection.

Brief description
-----------------

FFADE (FUBAR Approach to Directional Evolution) is a fast method to test
whether or not a subset of sites in a protein alignment evolve towards a
particular residue along a subset of branches at accelerated rates
compared to reference model. FADE uses a random effects model and latent
Dirichlet allocation (LDA) - inspired approximation methods to allocate
sites to rate classes.

Input
-----

1. A *FASTA* sequence alignment of protein sequences.
2. A *rooted* phylogenetic tree in the *Newick* format

Note: the names of sequences in the alignment must match the names of the sequences in the tree.


Output
------

A JSON file with analysis results (http://hyphy.org/resources/json-fields.pdf).

A custom visualization module for viewing these results is available (see http://vision.hyphy.org/FADE for an example)

Tool options

::


    --model            The baseline substitution model to use
                            [default] use GTR

    --branches          Which branches should be tested for selection?
                            All [default] : test all branches

                            Internal : test only internal branches (suitable for
                            intra-host pathogen evolution for example, where terminal branches
                            may contain polymorphism data)

                            Leaves: test only terminal (leaf) branches

                            Unlabeled: if the Newick string is labeled using the {} notation,
                            test only branches without explicit labels
                            (see http://hyphy.org/tutorials/phylotree/)

    --grid             The number of grid points
                        Smaller : faster
                        Larger : more precise posterior estimation but slower
                        default value: 20

    --method           Inference method to use
                            Variational-Bayes : 0-th order Variational Bayes approximation; fastest [default]
                            Metropolis-Hastings : Full Metropolis-Hastings MCMC algorithm; orignal method [slowest]
                            Collapsed-Gibbs  : Collapsed Gibbs sampler [intermediate speed]


    --chains           How many MCMC chains to run (does not apply to Variational-Bayes)
                            default value: 5

    --chain-length     MCMC chain length (does not apply to Variational-Bayes)
                            default value: 2,000,000

    --burn-in          MCMC chain burn in (does not apply to Variational-Bayes)
                            default value: 1,000,000

    --samples          MCMC samples to draw (does not apply to Variational-Bayes)
                            default value: 1,000

    --concentration_parameter
                        The concentration parameter of the Dirichlet prior
                        default value: 0.5
