These include pseudopotentials without non-linear core correction (e.g. for selected XC functionals, like TB09 also called mBJ that has proven to be comparatively the best DFT functional for band gap prediction of solids, see Borlido et al, J. Chem. Theory Comput. 2019, 15, 5069−5079), or pseudopotentials needed to reproduce results obtained in old publications. Please test them carefully before usage.
To use ABINIT in specific conditions it is recommended to produce your own atomic data sets.
This is the case, for example, if one wants to make simulations in specific thermodynamic conditions, or use specific exchange-correlation functionals, etc...
