But no lattice constant information. I can't find any lattice constant information in case.outputeos either. </div><div><br></div><div>I guess eosfit6 probably can do this job, however, I don't know how to use it. Before doing x eosfit, I did, parabolfit_lapw, but it always gives me errors. (see blow)</div><div><br></div><div>I hope you can give me some idea.
