Readme for tlynx-0.5.1.0

[back to package description]

The ELynx Suite

Version: 0.5.1.0. Reproducible evolution made easy.

A Haskell library and tool set for computational biology. The goal of ELynx is reproducible research. Evolutionary sequences and phylogenetic trees can be read, viewed, modified and simulated. The command line with all arguments is logged consistently, and automatically. Data integrity is verified using SHA256 sums so that validation of past analyses is possible without the need to recompute the result.

The Elynx Suite consists of library packages and executables providing a range of sub commands.

The library packages are:

  • elynx-nexus: Nexus file support.
  • elynx-markov: Simulate multi sequence alignments along phylogenetic trees.
  • elynx-seq: Handle evolutionary sequences and multi sequence alignments.
  • elynx-tools: Tools for the provided executables.
  • elynx-tree: Handle phylogenetic trees.

The executables are:

  • slynx: Analyze, modify, and simulate evolutionary sequences.
  • tlynx: Analyze, modify, and simulate phylogenetic trees.
  • elynx: Validate and redo past analyses.

Documentation is available on Hackage (use direct links above).

ELynx is actively developed. We happily receive comments, ideas, feature requests, and pull requests!

Installation

ELynx is written in Haskell and can be installed with Stack.

  1. Install Stack with your package manager, or directly from the web page.

    curl -sSL https://get.haskellstack.org/ | sh
    
  2. Clone the ELynx repository.

    git clone https://github.com/dschrempf/elynx
    
  3. Navigate to the newly created elynx folder and build the binaries. This will take a while.

    stack build
    
  4. Run a binary from within the project directory. For example,

    stack exec tlynx -- --help
    
  5. If needed, install the binaries.

    stack install
    

    The binaries are installed into ~/.local/bin/ which has to be added to the PATH environment variable. Then, they can be used directly.

Substitution models:
-s "MODEL[PARAMETER,PARAMETER,...]{STATIONARY_DISTRIBUTION}"
   Supported DNA models: JC, F81, HKY, GTR4.
     For example,
       -s HKY[KAPPA]{DOUBLE,DOUBLE,DOUBLE,DOUBLE}
       -s GTR4[e_AC,e_AG,e_AT,e_CG,e_CT,e_GT]{DOUBLE,DOUBLE,DOUBLE,DOUBLE}
          where the 'e_XY' are the exchangeabilities from nucleotide X to Y.
   Supported Protein models: Poisson, Poisson-Custom, LG, LG-Custom, WAG, WAG-Custom, GTR20.
     MODEL-Custom means that only the exchangeabilities of MODEL are used,
     and a custom stationary distribution is provided.
     For example,
       -s LG
       -s LG-Custom{...}
       -s GTR20[e_AR,e_AN,...]{...}
          the 'e_XY' are the exchangeabilities from amino acid X to Y (alphabetical order).
   Notes: The F81 model for DNA is equivalent to the Poisson-Custom for proteins.
          The GTR4 model for DNA is equivalent to the GTR20 for proteins.

Mixture models:
-m "MIXTURE(SUBSTITUTION_MODEL_1,SUBSTITUTION_MODEL_2[PARAMETERS]{STATIONARY_DISTRIBUTION},...)"
   For example,
     -m "MIXTURE(JC,HKY[6.0]{0.3,0.2,0.2,0.3})"
Mixture weights have to be provided with the -w option.

Special mixture models:
-m CXX
   where XX is 10, 20, 30, 40, 50, or 60; CXX models, Quang et al., 2008.
-m "EDM(EXCHANGEABILITIES)"
   Arbitrary empirical distribution mixture (EDM) models.
   Stationary distributions have to be provided with the -e or -p option.
   For example,
     LG exchangeabilities with stationary distributions given in FILE.
     -m "EDM(LG-Custom)" -e FILE
     LG exchangeabilities with site profiles (Phylobayes) given in FILES.
     -m "EDM(LG-Custom)" -p FILES
For special mixture models, mixture weights are optional.

Simulate

Simulate phylogenetic trees using birth and death processes.

stack exec tlynx -- simulate --help

ELynx Suite version 0.5.1.0.
Developed by Dominik Schrempf.
Compiled on June 12, 2021, at 14:54 pm, UTC.

Usage: tlynx simulate (-t|--nTrees INT) (-n|--nLeaves INT) PROCESS 
                      [-u|--sub-sample DOUBLE] [-s|--summary-statistics] 
                      [-S|--seed [INT]]
  Simulate phylogenetic trees using a birth and death or coalescent process.

Available options:
  -h,--help                Show this help text
  -V,--version             Show version
  -t,--nTrees INT          Number of trees
  -n,--nLeaves INT         Number of leaves per tree
  -u,--sub-sample DOUBLE   Perform sub-sampling; see below.
  -s,--summary-statistics  For each branch, print length and number of children
  -S,--seed [INT]          Seed for random number generator; list of 32 bit
                           integers with up to 256 elements (default: random)
  -h,--help                Show this help text

Available processes:
  birthdeath               Birth and death process
  coalescent               Coalescent process

See, for example, 'tlynx simulate birthdeath --help'.
Sub-sample with probability p:
  1. Simulate one big tree with n'=round(n/p), n'>=n, leaves;
  2. Randomly sample sub-trees with n leaves.
  (With p=1.0, the same tree is reported over and over again.)
