<div>Dear Lukas,</div><div>Although the relevant parts of your input are missing, I guess that you set the keyword AUTO_BASIS AUX_FIT <some value>. This activates the automatic basis set optimization which is unfortunately not implemented for AUX_FIT basis sets. PBE runs through because this code is only called if the AUX_FIT basis sets are actually requested.</div><div>You will have to provide a suitable basis sets, for instance by using a smaller basis set of the same basis set family or from the basis sets in BASIS_ADMM* in CP2K's data directory. There are different files for different basis sets.</div><div>HTH,</div><div>Frederick<br /></div><br /><div class="gmail_quote"><div dir="auto" class="gmail_attr">Lukas C schrieb am Montag, 29.
