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'*

This will just refine the loop in the A chain.

You are probably assuming that Modeller numbers the residues in each chain starting from 1. It doesn't by default, although you can ask it to do so: https://salilab.org/modeller/10.3/manual/node30.html

Hello Ben thank you for your kind update:).
No I have taken this into account i.e. starting residue is 2 accordingly my starting missing residue is 89 so I made it 88.
Please let me know at least then which of the above I should be using for an oligomer meaning should i designate each chain? (I will take care of the rest of the analysis to manage your time.)
Thanks Ben:) Joel

...and I solved this problem:
when missing residue modeling an oligomer while restraining non-missing residues, the script must be run twice while changing the self residue range in the script subsequent to the generation of the fill.ini file since this file does not start the residue count over for new chains hence the error of: no such residue: 88.B since it needs to be renamed which in this instance is residue # 521.
