(a-b) A montage of nine 3D classes in x-y (a) and x-z slices (b). (c-d) 3D sampling functions of the corresponding classes in x-y (c) and x-z slices (d). Note 3D sampling function confirms that the classification is not biased by particle orientations, as different classes have similar sampling functions and are nearly isotropic in different orientations.
- My understanding is that I am looking at 9 different orientations of the complex – and that this means that the complex is resting on the surface at a different angles. Or does it mean that the complex has different conformations in the 9 different classes?
- I realise that I don’t understand what a “sampling function” is in this context.
