SLControl is a computer program which helps perform sophisticated single muscle fiber experiments. It was developed by Ken Campbell during his time as a post-doc in the Moss lab at the Department of Physiology UW-Madison. He is now an Assistant Professor in the Department of Physiology at the University of Kentucky.

The program runs under Windows (NT 4.0 or later) and implements real-time control strategies using a PCI A/D and D/A board (a DAP 5216a from Microstar Laboratories in the original configuration). Key features of the system are shown below.

• FREE
• Real-time sarcomere length control at rates of up to 2.5 kHz (ktr experiments, ramp-stretches.)
• Real-time tension control at rates of up to 5 kHz (force-velocity, ramp-stretches etc.)
• Pre-defined muscle length control at up to 50 kHz
• Up to 500,000 points per channel (force, muscle length, sarcomere length).
• Sophisticated analysis features: curve-fitting (regression and exponential), stiffness calculations, digital filtering etc.
• Automated analysis for large data sets.
• Flexible filing system for exporting raw data to Excel, SigmaPlot etc.
• Clip-board output for raw data plots (for exporting to PowerPoint etc.)
• Matlab support for those developing their own analysis tools
• Frequently updated - specialist options can be developed given suffient interest.

SLControl is provided with the best of intentions, but there is no guarantee that it works correctly under all condition. When new problems are discovered, they are reported on this page and every attempt is made to fix the problem in future releases. Nevertheless users who chose to use SLControl do so at their own risk. No warranty is implied or intended. This page last updated on 30th April, 2005 by Ken.
