<div dir="ltr">Thanks a lot for trying to help. I did exactly just that, the option you described renames duplicate chains in the structure, however, in my structure, there are no duplicate chains. There's an A and a B chain. When I copy combine, I get another structure with A and B as well. I want the second structure to have C and D instead, i.e. a unique chain ID that is different from the original model's chain. </div><div class="gmail_extra"><br><div class="gmail_quote">On Thu, Apr 19, 2018 at 6:43 PM, Elaine Meng <span dir="ltr"><<a href="mailto:meng@cgl.ucsf.edu" target="_blank">meng@cgl.ucsf.edu</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi Ahmad,<br>
See the previous reply: the combined single model will not have any two chains with the same ID if you use the option I described, which is the default. Make sure you are looking only at the final combined model, not the other starting models which may still be open.<br>
