Unfortunately, in academia the only correct answer to the question, ‘what is the right tool for the job?’ is the question, ‘what does your adviser use?’ Excel is not the optimal tool—I agree. But, it’s the tool (many) geneticists use, and it’s important to find a way to make it work /better/ for the purposes it is /being used for/, rather than taking up space complaining that it’s /not the right tool/.
