Simulation
- five figures to show simulation results.
  * Figure 1a: Gaussian phenotypes
  * Figure 1b: Balanced Binary (50% case rate)
  * Figure 1c: imbalanced Binary (78% case rate)
  * Figure 1d, 1e: Poisson phenotypes (37% and 92% zeros).

Flow charts
- flowcharts for analytical pipelines
  * internal GxE enrichment analysis
  * external GxE enrichment analysis (PEGS GxE-WAS included)
  * functional enrichment analysis
  * creation of VLA-Catalog
  * using the Cata-log
  * (pending) PEGS 2-way GxE-WAS in greater detail
  * (pending) adjust PEGS GxE p-values by putative GxE statistics (i.e., VLA's p-value).
