1. Monoregion scenario with no ERP personalization, where all nodes had the same ERP
2. Control scenario with no ERP personalization, where ERP nodes of certain defined anatomical regions where modified as reported in Loewe et al. 2015  
3. Regional scenario with ERP personalization, where each region had a single ERP value derived from clinical measurement
4. Continuous scenario with ERP personalization, where the ERP distribution was generated by interpolation of measured ERP data
5. Control scenario with fibrosis, where elements corresponding to regions of low voltage (bi<0.5 mV) where set as slow or non conducing elements
6. Continuous scenario with fibrosis, where elements corresponding to regions of low voltage (bi<0.5 mV) where set as slow or non conducing elements
7. Continuous scenario where ERP measurements with additional perturbation draw from a uniform distribution. The perturbations were 2,5,10 and 20 ms, and we repeated this set 5 times for P6

In summary, we provide the following data: 

Create a dynamic Courtemanche model

As we will modify the ionic parameters on a nodel basis you will need to create a dynamic Courtemanche model and then declare the variables (ionic conductances) you need to modify. In your openCARP installation folder, go to the `limpet` copy the Courtemanche.model file

```
cd openCARP/physics/model/limpet
cp Courtemanche.model Courtemanche_nodal.model
vim Courtemanche_nodal.model
```

Then add on top the parameters that need to be modified on a nodal-basis:

```
group {
  GK1           ;
  Gto           ;
  GKr           ;
  GKs           ;
  GCaL          ;
  factorGKur    ;
  maxINaCa      ;
  maxIpCa       ;
} .nodal();

```

Then you would need to recompile openCARP. In the terminal, go to your openCARP's top level folder:
```
cd openCARP/ 
```

Configure CMake with updated imp_list.txt via:
```
cmake -S. -B_build -DUPDATE_IMPLIST=ON

```
Run the CMake building process:
```
 cmake --build _build
```
 This will generate the `.h` and `.cc` files for your dynamic model inside `physics/limpet/src/imps_src`

**Note:** If you want to add or modify a model file after openCARP was compiled, it is possible to first clean the previous generated files during compilation by running `make clean` before recompiling openCARP.

If you compile your own version of openCARP, then you can modify the settings.yaml file, to point to your openCARP version with the dynamic model.
```
cd .config/carputils
subl settings.yaml  
```
Add the build name:

```
CARP_EXE_DIR:
    CPU: /Users/lm104/Documents/OpenCARP/opencarp/_build/bin
    NODAL: /Users/lm104/Documents/OpenCARP/openCARP_nodal_adj/_build/bin
```
You can check that the new dynamic model is there by calling bench
```
bench -—list-imps
bench —-imp Courtemanche_nodal  --imp-info
```
