[Alcantara Ortigoza, Marisol]

Dear Stefano, 

Both q2r and matdyn codes of the CVS version worked fine. I thank you
very much for your time and patience. Marisol.

The format has chaged .
Information about cell_parameters has been added and in principle you
should run
nscf+ph again.

However you can also manually add the information missing in the "dyn"
files.

The new files should have after the first line with the title and the
second line containing nat ntyp ibrav celldm1 ... celldm6 four more
lines containing symm_type
at(1,1) at(2,1) at(3,1)
at(1,2) at(2,2) at(3,2)
at(1,3) at(2,3) at(3,3)
followed by the remainder of the file.

in practice you should take the CELL_PARAMETERS section of your scf
input and put it after the second line of EACH "dyn" file, just removing
the label CELL_PARAMETERS
