Hi everyone, The linear response analysis with Abinit is correctly predicting the imaginary (negative) frequencies for my structure. When I run the anaddb module for those results I get some numbers for the thermodynamic properties, but, what is the anaddb code doing with those negative frequencies?...

Dear everyone, I'm a new abinit user and I'm trying to calculate the phonon DOS for a NiTi compound, but I'm not getting the same result as reported in the literature. I just modified the input files in the tutorials to match my system. The general shape of the PDOS looks ok, but the frequencies see...
