Hi Sebastian, measure center #0 Center of mass of 327 atoms in 1CRN.pdb (#0) coordinate system = (9.30, 9.77, 6.98) measure center #1 Center of mass of 284 atoms in 1a0m (#1) coordinate system = (14.23, 8.20, 7.07) move -4.93,1.57,-.09 model #1 coord #1 Note the reported centers are in the local coordinate system for each model. When you first open the two molecules both have the same local coordinate system. But after moving one relative to the other with the move command they have different local coordinate systems since move just moves the coordinate frame of that molecule, it does not change atom x,y,z coordinates.

Hi,

is it possible to center a molecule absolute? I have to molcules and want to center one in the absolute center of the other one. Or e.g. center both in coordinate system on 0.0,0.0,0.0 The "center" command only centers the camera. But I need to move the molecules, not the camera view.
