[DFTB-Plus-User] No file name eigenvec.out

Hi Kim,

this seems a problem (or feature?) on the ase dftb+ interface, I cannot
recall such error message coming from DFTB+ itself. In that case you
should try to write in the ASE mailing list, the maintainers of the
DFTB+ interface are not DFTB+ developers.

If you use the internal DFTB+ driver for optimizing (which I suspect may
be faster) you would get your geometry as .gen and .xyz. dftb+ would not
care whether you want to write eigenvectors or not, this information is
not used for restart, only for post-processing.
