checking my understanding here : "add terminal residue" cannot be used for breaks in protein chains, right?

i.e. "add terminal residue" is for the N or C terminus of a unique chain (e.g. " A ") even if there's a gap in that chain

e.g. NH3-1-240 [ nice electron density here] 245-CO2 cannot have residues 241-244 built into it.

As far as I'm aware, you can build residues in a missing loop. The only requirement is that you don't have an isolated residue. For instance, you have residues 1-100, 105, 110-200 (you are missing residues 101-104 and 106-109). In such case, the only residues you can build are 101 or 109.

At least this is what I noticed (old version though).

Kind regards.
