I guess this is the old fashioned way, but it seems simpler to me!
There are 2 strands labelled T
I find it easier to run a program than use coot.
distang xyzin 65*pdb
RADI CA 3
end
This shows you that A 85 -ish is linked to T 11-23 with symop
X-1/2,-Y+3/2,-Z
and B ??? is linked to T 41-53 with symop X-1,Y,Z
Then I run
pdbset xyzin 65*pdb
SYMGEN X-1/2,-Y+3/2,-Z
end
And that gives me the symmetry equivalent of T 11-23 which I want.
With an editor I cut out those residues, and replace the ones in the
original file.
Then repeat the exercise with
pdbset xyzin 65*pdb
SYMGEN X-1,Y,Z
end
and cut and replace T 41-53

(PS - use COOT though to check that the new coordinate file exactly
overlaps the old one! A typing error is a disaster..
