Hi Angshuman,

The logfile you attached says that Athena is using Larch and that is where the error is coming from.  
A few comments on that: 
  a) it looks like it is using Python 2.7 which actually has not been supported for xraylarch for some time now (well over a year)
  b) that the `pyfai` module is not installed, which should not be required but is what is causing the actual error.

Having `pyfai` not installed should not cause an error, but this all suggests that your xraylarch installation is quite all.  
I would suggest reinstalling xraylarch using Python3 and see if that fixes the problem.

Dear sir,
I am new to this mailing list and excuse me if the question had already been asked. I am not able to import data in the Athena software. I tried to import some of the examples data like Fe_lepidocrocite.000 in the Fe standards folder while importing the data I encountered an error (screenshot has been attached along with the log file generated in the terminal).
I am using Linux Mint 18.3 Sylvia OS and perl 5, version 22, subversion 1 (v5.22.1).
I followed the instruction for installation here "https://bruceravel.github.io/demeter/documents/SinglePage/demeter_nonroot.html"
I will be thankful if you could suggest something to getting rid of this issue.
Thank you
