Dear Matthieu:

 I'm using only Gamma k-point as the cell is large. The calculation is so big 
that I cannot afford more than 15Ha cutoff, I know that 20Ha is enough for 
smaller systems so I hope to get meaningfull results. 
 Anyway, I made a new calculation using the last SCF cycle occupations from 
the first run, and I still get totally wrong ETOT (-5953.3796815118, I got  
-5948.7260884049 in the run which generated new occupations). So, I do get a 
lower energy with old occupations, but still away from -6222.6028568155, 
which was the last energy in the first run. 
 I will try to do the same thing with smaller systems.

Regards,
 Alexander
