You don’t need necessarily to use AUXSCORE to get Ambient Dose Equivalent.
If in your USRBIN you choose to estimate the quantity “DOSE-EQ”, you will obtain the Ambient Dose Equivalent rate using the “AMB74” coefficients (slide 7).
You need an AUXSCORE card only if you want to select a different set of conversion coefficients, see the AUXSCORE card manual.
If you want to know the contribution to a specific quantity give by a specific type of particles, you can also use AUXSCORE. If you select “NEUTRON” as particle, then you will only get the contributions by neutrons.
