I'm new to DSV 2.5 and would be grateful for help on the following matter. As a test exercise, I decided to view a sodium chloride .mol file (2D file from NIST, 7647-14-5-2d.mol) on DSV. The underlying .mol file lists the XYZ coordinates ("Original" coordinates) of (0,0,0) for Na, and (1,0,0) for Cl (i.e. distance of 1A between atoms). When I open the .mol file with DSV, the DSV atom data table displays the atom XYZ coordinates ("New" coordinates) of (-1.132, 0.817, -0.817) for Na and (2.133, -0.817, 0.817) (i.e. distance of 4A). If I click Save under DSV, the saved .mol file will have the New  coordinates. Can anyone explain why the XYZ coordinate change? Thanks for your help.
