Re: error while using dymmatrix.pl
Since I cannot link vtstcode to vasp binay right now,

can you please suggest if there is any way to generate normal mode movie files (or to create modes.dat) by using vtst scripts?

Re: error while using dymmatrix.pl
Dear Dr.Graeme, Now, after dynamical matrix calculation by modifying INCAR with ICHAIN=1(my objective is to generate movies for each normal mode), NSW=49(16 atoms in unitcell), POTIM=0.0, IBRION=3 (keeping remaining tags as it is from relaxation run) and its a single image calculation, while I am ru...

error while using dymmatrix.pl
error is:
Illegal division by zero at /../dymmatrix.pl line 166
line 166 is:
$matrix->[$current_displacement][$this_displacement] /= (sqrt($mass[$k]*$mass[$i]));
as I dont know perl scripting, pls anyone comment on why $mass[] is coming as zero.?
Thanks in advance.
