<div dir="ltr">Hi again Elaine,<div><br></div><div>I have a second question apart from the Utility enquiry. </div><div><br></div><div>I would like to first superimpose different SDF files (e.g. 1.sdf, 2.sdf, 3.sdf) of the same molecule [<b>Biotin:</b> a small molecule and not a protein] and then show conformational changes from one SDF to the other. However the program is not letting me do this as the molecules do not contain nucleic or amino acids. <br>
<br>How can I do this with commands?<br><br>Thanks again,</div><div style>Noel</div></div>
