Here it is decided what kind of map will be calculated. A Patterson Fobs map requires only a square of FOBS with zero phase. For any case first clear the map and convert it into a complex map. If the map shift is not zero, this is a good indication that something went wrong. Finally you can write the map to a file or look at it on the screen.
Kicked atoms are with increasing length of the kick less and less dependent from each other.
An equivalent of a kick is a molecular dynamis run at high temperature. The difference however is that kick acts instantaneously and that after displacment atoms are returned back to their initial positions. Structure factors calculated form kicked atoms contain less model bias. Since the procedure takes about a minute it can be applied very often during an interactive session and the resulting density may help you through dubious places.
