This tutorial is very similar to the [[Monoenergetic proton pencil beam]] tutorial. It is recommended to follow that tutorial first because some steps are similar. |

| - | Similarly to the previous tutorial you can plot the data in '''DoseLongitudinalMesh.txt''' and '''DoseLateralMesh.txt''' which were created using commands '''/score/''' in the macro '''proton.mac'''. The file '''DoseLongitudinalMesh.txt''' will be used later to compare with data from the Clatterbridge Cancer Center. Now, use script '''PlotLateralDoseMesh.C''' to plot the lateral dose distribution. | + | You can also plot the file '''PlotDose.txt''' using MATLAB. Similarly to the previous example first copy the text file to your computer. In the terminal at your computer write: |
| + | |||
| + | <pre style="color: #800000; background-color: #dcdcdc"> | ||
| + | scp username@plus1.hep.ucl.ac.uk:/home/username/ProtonGBFolder/ProtonGB_build/PlotDose.txt . | ||
| + | </pre> | ||
| + | |||
| + | Then, open MATLAB and follow the procedure: | ||
| + | |||
| + | * Import the file: Chose 'HOME' tab and 'Import Data'. | ||
| + | * In the 'Import Data' window select the 'PlotDose.txt' file choosing the right path. | ||
| + | * In the opened window select the data points in the 'IMPORT' tab. If you like, you can change the name of the variables. For example, 'x' instead of 'VarName1' and 'Dose' instead of 'VarName2'. Then, press 'Import Selection'/'Import Data'. | ||
| + | * Close the Import Window and in the Command Window type plot(x,Dose). Press Enter. | ||
| + | |||
| + | This plot will be created with added axis labels and a legend: | ||
