I've tried to generate a PAW potential using this dataset: https://www.abinit.org/ATOMICDATA/071-lu/index.html, atompaw 18.104.22.168 and LDA.
It results in an error:
I've contacted Prof. Natalie Holzwarth about it, and there seems to be no easy fix.Eigenvalues of overlap operator (in the basis of projectors):
The overlap operator has at leat one negative eigenvalue!
It might be not positive definite...
Program is stopping.
(The one we tried failed dramatically).
At the very least, the v1.1 dataset is questionable as is and I thus recomment using JTH v1 Lu from, e.g. http://www.pseudo-dojo.org, which works fine (at least, with Quantum Espresso).
Also note that the "bad" dataset results in a pseudopotential file using some older versions of atompaw - the overlap operator check was added only recently.
Thus, the fact that older atompaw produces the potential does not mean the potential is good.
