Florian, Based on your description, I think you might not be getting the selections right. Try:
Ctrl-shift left click on the first atom Ctrl-shift right click on the second atom Then control-T to bond (tie) them together. Cheers, Warren -- mailto:war...@delanoscientific.com Warren L.

They are in the same molecule and in the same chain. However, the connection is between a the carbonly carbon of a Gly and an oxygen atom of a segment which I called SEG. This is because the protein undergoes a backbone rearrangement, forming an ester. Anyways, I always get the error message: "Editor error: Invalid selections, requires two bonded atoms in the same moilecule". As I said, the atoms should be in the same molecule. Does anyone know a way to connect these atoms? Also it would in general possibly be nice to be able to connect atoms which are not in the same molecule (covelently bound ligands etc.) Thank you, Florian ---------------------------------- Florian Schmitzberger Department of Biochemistry University of Cambridge 80 Tennis Court Road CB2 1GA Cambridge Tel: +44 1223 766029
