You can do it with the "Change Chain IDs" graphical interface, open from menu: Tools... Structure Editing... Change Chain IDs. That dialog will list the chain with no ID separately (something like "principal chain") and you can click to choose it in that interface, then enter a new ID.<br>

I tried using 'changechain' command but I am getting error messages because I don't have any specific from-chain id. I don't know what exactly to give as from-chain id or is there any other command that could help me?<br>
