Hello,
When I further refine my structure the N+1 is gone and it becomes a
normal N again. So it is very much possible this is related to geometry.
Thanks everyone (Esp. to Jon) for the input!

Hello Sam
thanks for the pictures. It looks like the guanidinium group of the first Arg
is not very planar. I don't know the detailed nuts-and-bolts of how Coot and
Refmac handle this but the problem may arise from the initial geometry at the
affected nitrogen being off-target.
Best wishes,
Dear all
I attach herewith the Arg concerned. I actually saw no issue in Coot when I
checked residue info. The issue was repeatable using both Refmac from Coot
and from CCP4i. I rectified the issue simply by changing "N+1" back to "N"
using a word editor, but would surely be glad to know more
Hmm - I have never seen anything like that - the monomer for ARG has no N+1
elements..
Garib? Rob?

Hello, can you possibly show us a couple of screenshots with atom labels of the
affected side chain and a normal one?
