5. Create a steering text file (to avoid manual input). <br/>
# Step 2: Filter events containing charged particles from the Geant4 output files (discarding neutrons and photons)
Run the executable produced from FilterExtrAp.f best with a steering text file. <br/>
Example with the executable produced above and the sample steering file **cox.dat**:
$ ~/bin/FilterExtrAp < cox.dat
The first two lines are the numbers of files per case (PMMA thickness and primary energy) and of subdirectories (each corresponding to a combination of PMMA thickness and primary energy). The third line is a flag that should normally be set to 1.
# Step 3: Run the simulations
1. Download the data file **nanodosimeter3_eff_HIT_1.2mbar-C3H8_drift_V4c_part-1-2_ds2v4508.dat** which contains the detection efficiency map. <br/>
2. Create a text file containing the info on the simulation parameters. <br/>
An example is provided here as the file **HITEIN_240513.txt**. It may be necessary to change the last line of the section "DETECTION EFFICIENCY" containing the path to the efficiency map.
3. Create a steering text file (to avoid manual input). <br/>
An example is provided here as the file **bco.dat**. (It will be necessary to change the first line to reflect the correct path to the text file containing the info on the simulation parameters.)
An example is provided here as the file **bco.dat**. (It will be necessary to change the first line to reflect the correct path to the text file containing the info on the simulation parameters.)
6. Open a terminal and navigate to the directory where the data files (produced by FilterExrAp) are situated. <br/>
4. Open a terminal and navigate to the directory where the data files (produced by FilterExrAp) are situated. <br/>
Start the simulation.<br/>
5.Start the simulation.<br/>
Example with the steering file bco.dat: <br/>
Example with the steering file bco.dat: <br/>
$ ~/bin/PTra_HIT < bco.dat
$ ~/bin/PTra_HIT <bco.dat<br/>
The output files of the simulation are written to the directory in which the filtered datafiles reside.
