+Introduction
+============
+
+My [[thesis]] project investigates protein unfolding via the
+experimental technique of [force spectroscopy][fs].  In force
+spectroscopy, we mechanically stretch chains of proteins, usually by
+pulling one end of the chain away from a surface with an [AFM][].
+
+For velocity clamp experiments (the simplest to carry out
+experimentally), the experiments produce "sawtooth" force-displacement
+curves.  As the protein stretches, the tension increases.  At some
+point, a protein domain unfolds, increasing the total length of the
+chain and relaxing the tension.  As we continue to stretch the
+protein, we see a series of unfolding peaks.  The [[GPLed|GPL]]
+program [[Hooke]] analyzes the sawtooth curves and extracts lists of
+unfolding forces.
+
+Lists of unfolding forces are not particularly interesting by
+themselves.  The most common approach for extracting some physical
+insights from the unfolding curves is to take a guess at an
+explanatory model and check the predicted behavior of the model
+against the measured behavior of the protein.  If the model does a
+good job of explaining the protein behavior, it might be what's
+actually going on behind the scenes.  Sawsim is my ([published][]!)
+tool for simulating force spectroscopy experiments and matching the
+simulations to experimental results.

+
+Getting started
+===============
+
+Sawsim should run anywhere you have a C compiler and Python 2.5+.
+I've tested it on Gentoo and Debian, and I'll write up a Gentoo ebuild
+soon.  It should also run fine on Windows, etc., but I don't have
+access to any Windows boxes with a C compiler, so I haven't tested
+that ([email me][/~wking/contact.shtml] if you have access to such
+a machine and want to try installing Sawsim).
+
+See the [[README]] for more details.
