It's the library:
https://doi.org/10.1107/S2059798320013534
And it is not something that is terribly easy to fix. Arginine just has
internal clashes so that plane is only flat sometimes. This is a lot of
what led to the "Conformation Dependent Library", which I don't think is
set up under CCP4
I am refining a structure at 2.2A resolution. I find that all my arginines show
distortion after refinement with refmac5 even though they fit into the density
really well.
This is latest version of ccp4 8.00 running on windows 10. Is my library
messed up in refmac5? Any other ideas?
