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

Kharche S, Yu J, Lei M, Zhang H (2011) A mathematical model of action
potentials of mouse sinoatrial node cells with molecular bases.
Am J Physiol Heart Circ Physiol 301:H945-63

These model files were contributed by Sanjay Kharche

Use:

This is a standard C program that should work with most compilers.  To
compile with linux type

gcc -lm Kharche_SAN.c

to run type:
./a.out > stdout.txt

The program will write a voltage trajectory, mousesan.dat, simulating
the mouse SAN cells.  This trajectory contains (the start of the file)
waveforms similar to the figure 2A:

and (the whole file) figure 3B in the paper:
