Hey Elaine,

Thanks for the mail.

Just open the file in notepad and save it as .xyz (dont need to do that I am
attaching the file here now)
Then I have just opened this  .xyz file  in chimera and chimera loads the
desired image(attached: open with notepad or any text editor)(I have also
attached the output image of chimera)

Now my question is that
How do I use the script calle xyzmap.py on the following link
for opening the above file from the command line.
what should I replace the 'xyz_path' and the 'xyz_list' in the xyzmap.py
code with?
