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:0.980
Traceback (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.
