The KGG is developed for a broad spectrum of researchers and scientists, especially for those who are into pre-clinical drug discovery, understanding disease mechanisms/comorbidity and drug-repurposing. Although KGG is a programmatic tool, it comes with a user-friendly interface to take just a couple of input from a user to run the underlying scripts and methods.
