I think it's just that they are good at biology, not computers. I mean if they entrusted ME to tell two amino acids apart by looking at their behaviour, I'd take a month!

From what I've seen, amid all the research, failed experiments, constant fight for funding (in some cases) and "life" in general, people have much less time to learn these critical things like programming / tools so useful to them. They will do it at some point, but probably not till their life depended on it. On the other hand, if life depended on me recognizing those amino acids, we'd all be :-)
