go back to Main Page, Computational Resources, Scripts, Scripts for VASP

The script nfreq.sh extracts the vibration frequencies and the normal modes of vibration from an OUTCAR file of vasp version 4.6 or higher. You can multiply your initial cell and visualize the frequencies of the whole crystal.


Launching: nfreq.sh OUTCAR (no comments needed)

Output file: MOLCAR (to be visualized by molden)

Used files/subprograms: x.Cell



INSTALLATION STEPS

1) First of all, download the program:

      File:Cell.tgz

uncompress it and compile it: f77 Cell.f -o x.Cell. Place it in a directory of your choice (for simplicity, named directory A).


2) Download the script:

      File:Nfreq.tgz

and uncompress it.


3) CHANGE IN LINE 17 OF ngeom.sh path=/home/lbellarosa/bin/exe/Cell with the path of where you put your directory A.


4) Now you can run the script typing:

      nfreq.sh OUTCAR
