How to plot phonon dispersion from GULP output files

GULP
1

Dear GULP users,
I am new to using GULP and currently working on calculating the phonon dispersion of my system. I would also like to visualize the corresponding eigenvalues. However, I am not sure how to extract and plot the phonon dispersion data, or how to visualize the eigenvectors.
I have attached my .gin input file for reference. If anyone has experience with this or can guide me through the process of plotting phonon dispersion and visualizing eigenvalues, I would be sincerely grateful.

Hi Abid,
You should be able to view the files produced by “output phonon” using gnuplot, though there may be other more specialist ways of viewing them as well (obvious Materials Studio is one option). You can also output “castep_phonon” and so use any visualisers that support this for CASTEP.
Regards,
Julian
