hi
i've used them in my MSc research and my PhD research. it's all good. MSc was set up by a very nice gentleman in the department. PhD was on my internal web pages at my uni although the next couple of stages will be i think on QM Perception which is available through my uni.
there are quite a lot of papers on this kind of thing in the social science journals.
also, i think this has been discussed before and some people mentioned some free websites you can use if your uni doesn't have available software.
have fun!
A
