How to recognize HCP structure and dislocation using ovito?

[utt]

Sorry, somehow I posted my reply in the wrong thread:

A bug occurred when export to lammps data file

I checked your files and even the unit/super cells are not recognized as HCP phase by OVITO. What c/a ratio does your material have? OVITO usually expects a c/a ratio reasonably close to the ideal 1.63. Are you sure you handled the rotation and cutting of your unit cell correctly?

I saw your reply in the other thread:

Maybe your respond the post ? The material’s a is 4.709 Å and c is 7.442 Å. c/a is1.5804. I am sure the rotation and cutting is correct.
