                    <details>Asymmetric reconstruction without alignment was performed on each of two subsets (randomly assigned) from an ACP domain density-containing class after focussed 3D classification. This led to the generation of two half-maps, which were used to generate a sharpened map from all the data.

Note that the number of particles given above includes particles contributing to multiple symmetrically redundant orientations, as particles were generated through focussed 3D classification.</details>

Classification was performed in RELION 3.0.7, without alignment, and a regularisation parameter ('T' number) of 40. 

A class containing high-resolution density corresponding to the ACP domain was selected and particles in this class were used for a final reconstruction without alignment.</details>
