WitrynaYes Symmetry C1 (If you don’t know what the symmetry is, it is probably best to start with a C1 reconstruction. Also, some higher-symmetry objects may be easier to solve by SGD in C1 than in their correct space group. This data set is great data, and would also work in the correct point group D2. Witryna11 maj 2024 · Correct, symmetry expansion only means anything if the particles/reference are aligned to the (conventional) axis (axes) of symmetry, such as after a symmetry-imposed refinement. For cyclic groups, the symmetry axis is the map Z-axis. For other groups, the first axis is the map Z. For example, for Dn groups, the C … flag automatic weapon t shirt https://eliastrutture.com
