`generator.R`: simulate the external data and the trio dataset

`simulator.sh`: run generator.R and save the simulated results, and further perform analysis using other python-based methods (e.g. MR-Twin, MR-sib, MR-duo)

`benchmark.R`: contains all the neccessary code needed to replicate the results in the simulation in the main paper and the supplementary

`benchmark\_run.sh`: run the method benchmarking (MR-Twin is also partially re-implemented using R for the ease of comparison)
