Thank you for making it free for academic use! </div><div><br></div><div>I just have a quick question regarding the possibility of "filling-in" or changing the linewidth of ribbon structures. I would like to have my ribbon structures completely filled in and not hollow, so when I view them with "Side View" opition, I don't see emptiness inside.</div><div><br></div><div>I've attached two photos. The first is a view of the ribbon structure from the outside. The second is a view of the ribbon structure view from the inside, where you can see that it's hollow. I would like to know what function or command to use to correct this so it's complete solid inside. </div><div><br></div><div>Sincerely,</div><div><br></div><div>Alex Yorn</div><div>PhD Candidate </div><div>Department of Molecular Biology</div><div>University of Toronoto</div></div></body></html>
