The structure factor applet has four windows. Top left is the control window, in which you can select reflections and set their values by entering values in the text boxes. Several buttons allow you to modify the structure factor values in the map and the diffraction pattern. Top right is the structure factor window, which shows the current diffraction pattern. Bottom left is the reflection window, with which you can view or modify magnitudes and phases.
Bottom right is the map window, showing the unit cell and electron density.
Magnitudes and phases are encoded as colours using the same scheme as the Book of Fourier . Small screen or slow browser Miller Indices . Direct Methods . There are two versions of the structure factor tutorial. If you are not sure about your machine, try both versions and use whichever works better for you.
