My previous experience has been mainly with Gaussian and GaussView, so I am new to CP2K and periodic systems.<br><br>At the moment, I have the CIF file of the MOF. I am unsure how to correctly create the supercell and maintain periodic boundary conditions. If I generate a supercell in VESTA, I don’t know how to proceed afterward. For example, should I be removing atoms or layers, or is there a standard workflow I should follow?<br><br>Any guidance, references, or step-by-step advice on preparing the input coordinates for CP2K would be greatly appreciated.<br><br>Thank you in advance for your help!<br><br>Best regards,<br>Kinza</blockquote></div>
