Dear Mr Paulatto and Mr Gianozzi,
thank you for your replies.
In example with Force Theorem there are fully-relativistic nscf calculations
based on scalar-relativistic scf calculations. As far as I know, scf potential
should be also calculated with SOC to get correct potential. Am I wrong?
I tried to use the 'filepot' parameter and it seems to work (e.g. I did not get
errors), but with this parameter the scf cycle was only of 1 iteration shorter
than "normal" scf cycle with SOC.

It might be actually possible. Something similar is used in one of the

actually it is the charge density that is read. The G-vector grid for the

If I remember correctly the new file format writes in G-space, the old one
