Strategy 2

The crystal description was measured without indexing the faces (e.g. on an external microscope). The program EUHEDRAL should determine the orientation of the crystal shape with respect to the crystal axes.

Step 1

The refinement should be started with the command crystrot. The whole crystal description will be rotated with respect to the crystal axes (13 rotation axis). After input of start and end values of phi, step width, and angle criterion, EUHEDRAL calculates the number of crystal orientations to be tried. The program user then decides, whether this number is appropriate.

Alternatively you can use crystrotsimplex.

Further steps

Continue then with the (repeated?) refinements of volume and distances, as in Strategy 1.
