            <details>EMAN2 was initially used for particle picking, 2D classification, projection refinement and 3D reconstruction for both normal and isomeric hemocyanins with C5 symmetry imposed. Subsequently, 57,043 isomeric hemocyanin particles were imported to Relion-1.1 for further refinement and reconstruction by applying D5 symmetry, using the reconstructed map from EMAN2 as the initial model. Xmipp-2.4 was used for the? bfactor correction to generate the final 3D reconstruction map of isomeric hemocyanin.</details>
