I’m having porblems trying to model a structure and using the loop

help me with this error?
The error is:
_modeller.ModellerError: No loops detected for refinement: you must
redefine select_loop_atoms
This seems self-explanatory, no? Your model doesn't contain any loops
(insertions in the alignment) so there is nothing to refine. If there's
a region you still want to try refining anyway, you need to explicitly
define that by providing a select_loop_atoms function. See
