Hi,
thanks for your efforts Otis! What I want is not as fancy as Bob guessed. Let me try to reformulate what I want to achieve: "Use the mouse to rotate an arbitrary set of atoms around its geometric center.". I set up a page with some comments (also attached below) to clarify things, hopefully: http://weirdbyte.de/jmol-test/html/move.html Alex // comments from the website load "../data/3cap.pdb"; set selectionHalos ON; select chain=a; set dragSelected ON; set allowRotateSelected ON; Rotating (alt-left) and translating (alft-shift-left) of selected chain a works fine, only selected atoms are moved. This is what I want in general, a way to move (rotate, translate) only selected atoms using the mouse, but depending on bonding, I have not found a way to achive it (for translating I got it, but not for rotating) as I hope to show below load "../data/3cap.pdb"; set selectionHalos ON; select chain=a and plm; set dragSelected ON; set allowRotateSelected ON; Translating (alt-shift-left) works as expected, moves just the selected atoms (plm). Rotating (alt-left) moves plm and the bond protein chain=a, this works as documented "set allowRotateSelected FALSE - When set TRUE, this parameter allows user rotation of the molecule containing the selected atom using the mouse (holding ALT down while dragging). The coordinates of the rotated molecule will be sightly degraded in this process." However, I am looking for a way to just rotate the selected plm, regardless of weather it is bond to the protein chain a. load "../data/3cap.pdb"; set selectionHalos ON; select chain=a and plm; set picking dragMolecule; The picking/drag approach, selection does not matter. Pick/drag the protein chain a moves just the protein chain a. Pick/drag plm moves the protein chain a and all bond non protein molecules, including plm. This is asymmetric, is there a rationale for that? Actually I do not mind, I just want a way to move (rotate, translate) only selected atoms using the mouse. ----- Ursprüngliche Mail ----- > Von: "Otis Rothenberger" <osrot...@chemagic.com> > An: jmol-users@lists.sourceforge.net > Gesendet: Dienstag, 9.
