Dear Pascal and prof. Gonze,

I have tried your suggestions (changed tolvrs in DSs 4-17 and use anaddb input
from tests/v2/Input/t22.ddb.in.gz), but with no success. The 2nd derivations 
do
not change significantly (ie. the phonon frequencies) with increased tolvrs.

I am dried out of ideas how to reproduce the results from the PRL article. I
can (for any case) send again (in the attachment) the inputs I used (and
xmgrace plot). The psudos are the same and I used even better ecut and k-point
mesh. I don't receive any warnings in the output file during these calcs,
except

I am very grateful for any response.

Thank you!
