[modeller_usage] Missing Residue and Loop Modeling Script Inquiry for an OLIGOMER

Hello, for the above topic I have a heptamer, accordingly should my missing residue code for chains A-G be just and A-chain indication with the B-G being modeled via default or should I designate each chain, see below:

return Selection(self.residue_range(`88:A´, `100:A´))

or

return Selection(self.residue_range('88:A', '100:A'), self.residue_range('88:B', '100:B'), self.residue_range('88:C', '100:C'), self.residue_range('88:D', '100:D'), self.residue_range('88:E', '100:E'), self.residue_range('88:F', '100:F'), self.residue_range('88:G', '100:G'))

I tried the later (A-G coding) and received the below error where there should be this missing residue?

*raise KeyError("No such %s: %s" % (indxtyp, indx))* *KeyError: 'No such residue: 88:B'*
