Hi, Sebastian.

I was running a simulation in TOPAS that generates me different .csv data files. Since they are several .csv, I created a macro in ROOT (in C++ language) to join all those data in a single .csv file to be able to use TopasGraphSim. However, when I upload it in the TopasGraphSim tool it does not load, it does not graph anything.
Why does this happen if it is still a .csv file?

The image on the left is one of several files that I want to join and that the TopasGraphSim tool does read and plot. The image on the right is the result of merging several .csv files into one which I load in TopasGraphSim but it doesn't read it, it doesn't recognize it.

Hi Diana,

TGS expects your simulation profiles to contain the following columns:

DoseToMedium ( Gy ) : Sum/Mean   Standard_Deviation   Histories_with_Scorer_Active   Count_in_Bin   Max

Honestly, I only really use the first three, so if you create a TOPAS-style csv file and fill the first three columns with your values, and zeros in the last two, that should work.
Alternatively, just create a .txt file with three columns - position in the first, dose in the second, and std_dev in the third. That will also work.

Feel free to send me one of your files, I'll sent it back to you edited in a way that works for me.

Best,

Sebastian

Hi, Sebastian.

I attach one of the files that I need to plot so that you please edit it so that the tool reads it correctly and with that I take it as a basis for the other files, since I have edited them in different ways but I can't get the graph, I don't know what I'm doing wrong.
According to what you say, from the attached file the three columns I need are the ones called: “X Axis”, “Absorbed Dose Rate (Gy/h)” and “Standard Deviation”.

Hi Diana,

The format you've sent me isn't the output of a TOPAS simulation, right? For TGS to recognize it as such, its missing the required headers. I've reformatted the relevant data from your file into a TGS-readable version, and attatched it below. Note that in the .txt file, there are no header rows, and the three columns are seperated by tabs. The first column is the x-axis position (perhaps you still need to adju this manually to represent your bin size), the second column is the dose value (be that sum or mean, doesnt matter), and the third column is the error you associate with the dose value (the value isnt manipulated in any way, and represents the size of the error bars on the graph, so make sure that its in the same units as the dose, not a relative value).

Let me know if you have any other questions!q

Best,
Sebastian

Hi, Sebastian.

That's right, the file I sent you is not the output of a TOPAS simulation.
Thank you very much for your help, I already get the graphs as I expected.
