</span>Dear Ti,<br>
I think you can use the “Change Chain IDs” tool (in menu under Tools… Structure Editing). If I recall correctly, even though you don’t already have chain IDs, the parts separated by TER will be listed separately in the dialog and you can specify a new ID for each.<br>

<br>
There is also a “changechains” to do basically the same thing, but it only handles chains that already have IDs that are different from each other.<br>

I hope this helps,<br>
