 Evaluation
 ============
 To evaluate the results of the simulation and generate a plot corresponding to the ones in figure 12 in the paper the following steps are necessary:
-We extract all values in the top grid cells of every vtu file by the [extractlinedata.py](https://git.iws.uni-stuttgart.de/dumux-repositories/dumux/-/blob/releases/3.2/bin/postprocessing/extractlinedata.py) script of dumux and store them in a new folder `PlotOverLine_Analysis`:
+We extract all values in the top grid cells of every vtu file by the [extractlinedata.py](https://git.iws.uni-stuttgart.de/dumux-pub/bringedal2021a/-/blob/main/bin/extractlinedata.py) script and store them in a new folder `PlotOverLine_Analysis`:
 
 ```bash
 cd bringedal2021a/
 mkdir PlotOverLine_Analysis/
-pvpython ../dumux/bin/postprocessing/extractlinedata.py -f build-cmake/appl/instability_1pncmin-* -o PlotOverLine_Analysis/ -p1 0 0.1999 0 -p2 0.6 0.1999 0 -r 600 -v 1

 ```
 Note that the option -f has to be adjusted to the name of the vtu-files, when using the bash scripts listed above to run the simulations. This data is needed to run the evaluation script which calculates the mean value and standard deviation of salt mole fraction at the top and plot them over time:
 ```bash
