 BioFindr is an implementation of the [Findr software](https://github.com/lingfeiwang/findr) in [Julia](https://julialang.org/). See our paper ["Efficient and accurate causal inference with hidden confounders from genome-transcriptome variation data"](https://doi.org/10.1371/journal.pcbi.1005703)[^Wang2017] for  details of the methods implemented in BioFindr.
