Virginia,

Looking at your script, I see that the quote characters surrounding 'align.ali' are not the same as the ones surrounding 'atom_files' four lines above it. The ones around 'atom_files' are correct; they are standard ascii single-quotes. All the later ones are wrong; they look like the smart-quotes that word-processors use for apostrophes, to replace the ugly single-quotes. The error message says that Python doesn't like those.

Make sure you are using a plain text editor with an ascii encoding to edit your file. You can find more explanations online, e.g. http://www.linuxplanet.com/linuxplanet/tutorials/6912/2/

I hope that helps, -Jonathan
