No problem! Actually, I'm pretty new to this stuff too, so explaining kinda helps it gel. Anyway, I'm writing something up now so I'm going to come back to this later, but I think what you want to do to get asymmetry is run a MANOVA or an ANOVA with size as your variable. You can do MANOVA in SPSS and there's quite a few tutorials online for how to do that. An ANOVA is possible in MorphoJ and probably your simplest and quickest option. Once you have everything in go to the "Variation" tab and it will be your last option. If you've loaded your classifiers you'll be able to assign "side" to the box that - most helpfully - is marked "side". If that's what you're trying to do it's quite easy. Many of the people on this list have published on it as well so the method is very nicely supported.
