************************************** Simulation Data ********************************

There are several raw simulation data files that we uploaded in this section. These data are simulations
of the FitzHugh-Nagumo (FHN), Luo-Rudy 1 (LR1) and Hund-Rudy (HRD) model for cell-to-cell coupling using 
subthreshold stimulus. These simulations are used to recreate the wet experiments done by Akar et al. (2001).
Simulations were done using either Dirichlet or Neumann boundary conditions.

The simulation results text files are arranged such that each space-separated value represents the membrane potential in a node position. Therefore, if the simulation morphology is a 100x100 mesh, the membrane potential values are also arranged in a 100x100 grid. There are several grid of values in the simulation results separated by a new line. Each of these grid represents the membrane potential values at different times starting at simulation time t=0 ms until t=500 ms.

The simulation results can be viewed using a graphing tool like Gnuplot. You will need the plot control files (*.plt) provided with the raw simulation results to do this. The following are the instructions for displaying the results in Gnuplot:

1. Start gnuplot 
	> gnuplot

2. Go to the directory where you saved the raw files and the *.plt files.

3. Initialize the value of the counter 'i' (value can be from 0 to 499)
	gnuplot> i=0

4. Load the pre-processing file                   
	gnuplot> load "RawLR1_animation_pre.plt"

5. Load the animation plot file                
	gnuplot> load "RawLR1_animation.plt" 

There is a loop in animation plot file that runs to t=100. If you want to terminate the animation, change  "if(i < 100) reread" to "#if(i < 100) reread" and save. This will comment out that line and terminate the simulation on the next iteration. The example above is for the Luo-Rudy 1 in 100x100 mesh simulation. The simulation file can be changed in the plot file. However, you may need to change the color range in the pre=processing file if you want to display simulation results using a different model.
