The input code is written in the case of only calculate all water molecules (see the atom indices 241..390 in the INVOLVED_ATOMS section). The system consists of a crystal system LiNbO3 (2x2x2 unit cells with periodic boundary) and a water system (~50 water molecules). After some attempts to run vibrational analysis calculation I got error message, that the Berry phase moments were not implemented:<br><br> CP2K| UNIMPLEMENTED, Berry phase moments for non uniform MOs' occupation numbers not implemented<br> CP2K| Abnormal program termination, stopped by process number 48<br> CP2K| UNIMPLEMENTED, Berry phase moments for non uniform MOs' occupation numbers not implemented<br> CP2K| Abnormal program termination, stopped by process number 51<br> CP2K| UNIMPLEMENTED, Berry phase moments for non uniform MOs' occupation numbers not implemented<br> CP2K| Abnormal program termination, stopped by process number 65<br>[...]<br><br>I have not idea what the reason is and I am looking for a help or hints to solve the problem.<br>The input file is attached here.<br><br>Kind regards,<br><br>Phil<br></div></blockquote></div></div></blockquote></div></div></div><div class="HOEnZb"><div class="h5">
