Masayoshi is correct: because you set ionmov, the first GS run did a
relaxation before finishing. This is certainly a bad idea, because the
new geometry will not be copied over to the other dtsets, and because,
as you saw, the file names are incorrect, with the TIMx added, instead
of the straight density file. You should separate your runs, and do
any relaxation and convergence testing separately before running the
RF.
