Figure 6
Density-gradient map (a), difference map (b) and shift field (c) for residue B90 of PDB entry 1o6a. The gradient map shows how the density would change for a uniform increase in B factor across the map. The difference map shows the changes to the density which would improve agreement with the observations. The shift field shows how the B factor would change as a function of position to improve agreement, using r0 = 3 Å. |
