The Luzzati plot ( R ‐factor against reciprocal resolution) is a useful way of assessing the reliability of a crystal structure. It is commonly employed in obtaining an upper limit to the error in atomic coordinates of a protein structure. The advantages of the spreadsheet program Microsoft Excel has been exploited and a simple procedure for producing high quality Luzzati plots for non‐centrosymmetric structures (such as proteins) has been developed.
