Structure of JWAS

  flowchart TD;
      A["phenotypes.csv"] --> A2(CSV.read) --> D(build_model)
      B["pedigree.csv"] --> B2(get_pedigree) --> D(build_model)
      C["genotypes.csv"] --> C2(get_genotypes) --> D(build_model)
      D --> E(set_covariate);
      D --> F(set_random);
      E --> H{runMCMC}
      F --> H

Help

1. Show this README file in REPL or notebook using ?JWAS
2. For help on a specific function above, type ? followed by its name, e.g. ?runMCMC and press enter.
3. Run Pkg.add(PackageSpec(name="JWAS", rev="master")) to get the newest unofficial JWAS. Run Pkg.free("JWAS") to go back to the official one.
