Hi everyone,
I was recently looking at the following structure deposited in the
PDB: 4g1m. Overall, the structure fits nicely the density, but the map
shows large red blobs inside some of the domains (negative density
disappears around 5 sigma). Could this be due to an excessive low R
factor that phenix.refine has generated: R=17.9 and Rfree=23.3 at a
resolution of 2.85 A?
