I couldn't agree more. I have been thrown into learning GROMACS and designing a coarse grain model from scratch (my background is that of an experimentalist, doing AFM pulling experiments, by the way!), all practically by myself. I mean: I *wanted* to learn all of that, I just didn't expect I would have done it *alone*. So I read the Frenkel-Smit book, the GROMACS manual, and banged my head a lot (luckly I was already experienced with Linux and programming). No wonder one year after, I'm just beginning to see where I am going *sigh*. m. Chris.
