Hi Nevin,

Thanks for posting this within the PyMedPhys community forums :slightly_smiling_face:.

At first glance I notice that you have very small numbers in use:

Would you be able to start by finding the slice where you have the most dose, plotting the evaluation and reference for that slice and see if it makes sense?

There’s a bit going on in your post, before addressing the other points it’d be helpful to get on top of what data we’re working with.

Also, the following how-to guide shows the calculation of gamma from a bit more first principles:

Once you have a slice pulled from your eval dataset, and a slice pulled from your reference dataset would you be able to run gamma over them in a way similar to that second tutorial?

Also, here is the raw Gamma API reference, which might be helpful:

Also, some other discussions around Gamma:
