Hi, Thank you for your answer. I deleted Ni and Mn alternately, but it didn't work. I obtained a new one from ICSD, and it is working fine. I have attached it. Having atoms in the same position was not a problem with other CIF files, like the FMN attached one. I am fitting now, but I was concerned about it. Thank you again for your help. Best regards.

The site in Mn and Ni in cif is same. It makes your problem. Make only Mn in cif. I mean that Mn instead of Ni is located. And run feff. You can get the path related with Mn. After that, Make another structure in same cif, Ni instead of Mn. You can get the path of Ni. Then, use them

Dear all. I am trying to generate the path for fitting Mn and Ni K edge at LiMn1.5Ni0.5O2 using cif files from ICSD. I receive this error:

*Elements: ['Li', 'Mn', 'Ni', 'O']Sites: [2.08337619 6.16682619 6.08352381] Li:0.980Traceback (most recent calls last): File "C:\Users\Me\xraylarch_2023_10\Lib\site-packages\larch\wxlib\cif_browser.py", line 447, in onShowCIF sites = ['%d' % (i+1) for i in range(len(sites))] ^^^^^^^^^^TypeError: object of type 'PeriodicSite' has no len()*

I also attached the cif.

Any hint to go forward?

Best regards.
