I already described the only methods I know. You would need to keep using the mouse or small "move" amounts until you achieve the distance you want.<br>

Or, if you want to move exactly horizontal and avoid imprecise manual movements, then you could use the "move" command with the "models" option to specify only moving a specific model.<br>

If I am thinking right, this would also require shifting the rest of the atoms of SER10.A towards SER 20.A in a similar manner. Is it possible to achieve this in chimera?
