 CuNA or Cumulant-based Network Analysis finds higher-order genotype-phenotype relationships from multi-omic data with EHR information across different thresholds of statistical significance.

+CuNA uses the Julia library [Cumulants.jl](https://github.com/iitis/Cumulants.jl) which in turn requires Julia to be in your `PATH` variable. Install Julia from the [Julia software page](https://julialang.org/downloads/) and set your `PATH` as `export PATH=$PATH:_path_to_julia_`
 
 ## Input
