Hello, I have been following the Materials API Youtube Tutorial hosted at UC Berkeley in 2020 through the following link.
In the final section, where potential vanadates are being screened for negative Poisson ratios, I discovered that the final material(MP-775001) determined to be the best candidate doesn’t have a Poisson Ratio value in the updated Materials Project page. I’m unfamiliar with using Pymatgen, so maybe the previous usage of “poisson_ratio” and now the current usage of “homogeneous_poisson” may be causing problems. If I could gain some clarity as to why MP-775001 had a Poisson Ratio of -0.06 previously and now doesn’t seem to have an accessible value through the new API, that would be greatly appreciated. Thank you!
