I'm working on dockprepping the sars-2 main protease and whenever I try and save it as a .py file, I can't open it from sources other than the saved session I wrote. Whenever I try and open it from a dropbox or my finder, I get the message:

Error while processing /Users/8642165/Desktop/Research/DC AP Research /[7l0d]DOCKPREPPEDFINAL.py:
  File "[7l0d]DOCKPREPPEDFINAL.py", line 1
    @<TRIPOS>MOLECULE
     ^
SyntaxError: invalid syntax

  File "/Applications/Chimera.app/Contents/Resources/share/chimera/__init__.py", line 1325, in _openPython
    loadFunc(sandboxName, fileName, f)

See reply log for Python traceback.

Is there any way that I can fix this problem?

Thanks, 

Henry Shook
