You may have already downloaded them when you installed G4. For example, my data files are in<br>
/usr/local/Cellar/geant4/10.5.1/share/Geant4-10.5.1/data (on macbook using brew)<br>
</div>
<div style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
so perhaps you can find them in an equivalent path or download them if necessary. I suspect if they are missing, there would be an error message when you try to use it?</div>

Dear GATE users,<br>
<br>
I am trying to simulate the energy deposition of a point source of Lu177, with user-defined spectrum.
<br>
In the GATE wiki website I read that "The download of radioactive decay data files is required.”, but I don’t know where to find them and then how to include them in the simulation. Also, here
<a href="https://github.com/OpenGATE/GateContrib/tree/06a240b36ca55b9ec00f852df65265109bba4859/dosimetry/dosimetry/protontherapy/mac">
https://github.com/OpenGATE/GateContrib/tree/06a240b36ca55b9ec00f852df65265109bba4859/dosimetry/dosimetry/protontherapy/mac</a> <<a href="https://github.com/OpenGATE/GateContrib/tree/06a240b36ca55b9ec00f852df65265109bba4859/dosimetry/dosimetry/protontherapy/mac">https://github.com/OpenGATE/GateContrib/tree/06a240b36ca55b9ec00f852df65265109bba4859/dosimetry/dosimetry/protontherapy/mac</a>>
they don’t seem to download/include these radioactive decay data files, event though they actually use the RadioactiveDecay process.<br>
Can please someone explain me what to do to simulate a radioactive decay? <br>
<br>
For completeness, I copy here the “Physics” section of my macro:<br>

<br>
Thank you for your help!<br>
<br>
<br>
Best regards,<br>
