Kymograph: a muscle physiology toolkit.

Kymograph is a freely available, Linux-based data acquisition and control system that is designed as a device driver and a series of scriptable tools. It allows the creation of scripts for performing a variety of measurements related to muscle physiology. It can control hardware (2 analog channels) and capture data (up to 16 channels) at rates of up to 1 kHz. It also has the ability to generate stimulus control pulses with a resolution of 10 micros. The tools can be used with any of the common scripting languages to generate complete control and capture routines for performing measurements such as length-tension curves or force-velocity relationships. Source code is provided to allow easy extension of the software.
