I see, thank you.
I've run it and got a number of bad profiles (but mostly great ones, which is awesome!) in results.['profiles'].['radius'].
I'm going to rerun it with the cpoint specified.
I've aligned the trajectory based on the atom selection that defines the pore so the center point is almost exactly the same between each frame.
Do I just leave that one specified point to refer to all frames across the trajectory or is there a way to have cpoint updated each frame?
Thanks again!
