<div>(Sometimes, I program displacement images in Mathematica.)</div>
</div><div>Again, using "visualize" is not clear.</div><div><br></div><div>I hope, these comments would help you to attract attention of the developers.</div><div><br></div><div>Victor <br></div><div><br></div><div><br></div><br><div> <br></div><div><br></div><div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, Jun 28, 2023 at 10:06 AM 'RASHMI BRAHMA' via cp2k <<a href="mailto:cp2k@googlegroups.com">cp2k@googlegroups.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">Hello<div><br></div><div>I am new to cp2k, and I keep getting negative frequencies even after optimization of the coordinates of my system.
