Hello everyone

I am new using the GULP module. I am trying to get a .eig file with the information of the phonon frequencies and eigenvectors for a supercell. However I am not able to find any option in the setup of the GULP calculation to obtain this output file. I have been trying to modify the input file by myself, but I do not get the correct command or line option to activate the eigenvectors keyword. I hope someone can give me a hand in how to get the .eig output file after the phonon calculations in GULP. By the way, I am running a constan pressure relaxation.
