<br>
Performing phonons on gamma-boron at 30 GPa (using GGA), I have this message:<br>
from set_irr_sym_new : error # 2111<br>
wrong representation<br>
<br>
I send down the atomic positions as I know from previous mail (Lorenzo<br>
Paulatto 2012-07-23) that you need some tests to find a reliable way to<br>
generate the initial random pseudo-dynamical matrix (random_matrix.f90).<br>
Lattice and atomic positions are already converged.<br>
<br>
Increasing the threshold 10^-6 to 10^-4 line 156 and 158 of set_irr_sym.f90<br>
does not solve this issue.<br>
<br>
Do you have any other suggestion?<br>
<br>
Thank you very much<br>
