I have to detect AA location within MAP (density) 3D matrix. And to verify with PDB format (which models same 3D structure). Each AA may have different rotamer (aka 3 angles usually used to describe AA exact position related to carbon C_alpha atom (the atom which AA side chain exits from). To justify inaccuracies - I need to show that (among other reasons) - inaccuracy is caused since not all possible rotamers existed in my training set (I use machine learning classification to decide what AA is it, and where it stands within cryo- EM scan).
