This is the readme for the model associated with the paper:

Greenstein JL, Hinch R, Winslow RL (2006) Mechanisms of
excitation-contraction coupling in an integrative model of the cardiac
ventricular myocyte. Biophys J 90(1):77-91
doi: 10.1529/biophysj.105.065169

This model was contributed by JL Greenstein.

To run: extract this archive and run the command "Script_40state" in
matlab.  After a short time this image should appear:

When the axes are zoomed in to the first 400 ms this is similar to the
solid curve in Fig6 A in the paper:
