[Biojava-l] modify structure

[Tamas Horvath]

If I've got a Group , which is an amino acid, and I want to shift it by a 3Dvector (or 3 2D vectors), how may I do it?Similarly, if i want to rotate the same structure, how may I do it?If you just can show me a very short sample code, I'd really appreciate it!Thanks!
