FOGEN produces any volume of space from an electron density map containing a minimum of one asymmetric unit of real space. The output map may be scaled and then printed, stored on a bdf, or both. If the map is to be printed, all values may be listed or any character may be substituted for values lying between certain user-specified limits. There must be sufficient memory available to store the entire input map plus one complete section of the output map. FOGEN is applicable to all space groups.
