Example of a normal probability plot. The B factors of the 14 atoms of Trp28 in PDB entries 3tmx and 6qwx, shown on the right in Å2, allow a plot of d versus de (circles) to be made, which has a slope a of 2.246. Obviously, the of plot d/a versus de (stars) has a slope a of 1 and implies an average standard error of 1.59 Å2 for the B factors. |
