Hi all,

         I am trying to fit Cd kedge EXAFS data of CdO and CdO-CaO solid solution.

Like many others I ended with “Hard tests failed in fovrg. Muffin-tin radius may be too large; coordination number too small“error.

Professor John, mentioned this may be due to insufficient grid size in calculating the phase shifts and he advised to post the "feff.inp", to have a look at it. But I have 38 feff.inp files in total (corresponding to CdO, solid solutions of CdO-CaO at various compositions and for dopents as well). I feel it will be hard to look into this may files, for any one.

         I will be thankful if anyone help me, in how to overcome this problem. Here with I am attaching the "feff.inp" of CdO. Please tell me how to modify feff.inp file such that I can do myself for the rest of feff files

Thanks in advance.
