The first thing that a non-crystallographer should be aware of is the existence of the temperature factors. It is a pity that the displays of biological macromolecules on the data bases do not show these. These temperature factors clearly indicate which areas of the molecule are more/less "ordered" and more/less reliable (there is a correlation between the 2, when one gets to regions of high isotropic temperature values, I'm not talking of differences between an isotropic B value of say 15 and one of say 17). I personally like to visualise the electron density as well, however, I do think that a non-crystallographer will go through the trouble of downloading the structure factors, installing ccp4/coot etc. Fred.
