BCC Interstitial Defect Classification Code

This codes can classify if the given structure is bridge dumbbell / bridge crowdion / <111> dumbbell / <111> crowdion based on their characteristic patterns in bond angle distribution. Restrictions 1.

This code only works with bcc structures with 129 atoms that contains a interstitial atom. 2. The atom coordination file should be edited to feed. 3. This code cannot identify different defect types except defect types specified above.
