Electron-density analysis of crambin refined at truncated resolution. The 2mFoDFc electron density at the 1.0σ contour level of polyalanine models around residues Val15, Cys15, Arg17, Lys18 and Cys26 of the deposited structure of crambin. The map R factor along the crambin chain was calculated residue-by-residue between the Fc map of the final deposited model and the 2mFoDFc map of the refined polyalanine model. The electron-density R factor ranges from 0.28 (blue) to 0.67 (red). (a) ML CV electron-density map using a 5% test set. (b) ML FK electron-density map using a 1% test set. (c) Residue-by-residue map R factor of ML using a 5% test set. (d) Residue-by-residue map R factor of ML FK using a 1% test set.
