Kymograph is a free, Linux-based system for muscle physiology research. This software enables precise control and data capture for experiments like length-tension and force-velocity measurements.

Area of Science:

  • Physiology
  • Biophysics
  • Software Engineering

Background:

  • Muscle physiology research requires specialized tools for data acquisition and hardware control.
  • Existing systems may lack flexibility or be prohibitively expensive.

Purpose of the Study:

  • To introduce Kymograph, a versatile, freely available data acquisition and control system.
  • To provide researchers with a scriptable tool for muscle physiology experiments.

Main Methods:

  • Kymograph operates as a Linux-based device driver and a suite of scriptable tools.
  • It supports control of 2 analog channels and data capture from up to 16 channels at 1 kHz.
  • Stimulus control pulses can be generated with 10-microsecond resolution.

Main Results:
