Hooke is a force spectroscopy data analysis package. For example, Hooke can extract unfolding forces from your experimental data. You can then fit the unfolding forces to models using my sawsim simulator. Of course, some experiments (e.g. force clamp) need no Monte Carlo analysis, so for those, Hooke alone provides a complete analysis package.
I've tested Hooke on Gentoo and Debian, and I've got an ebuild in my Gentoo overlay. It should also run fine on Windows, etc., but I don't have easy access to Windows boxes with Python, so I don't test it there as often.
