There are three submenu options for the Calculate Anomalies menu which produce raster maps of the gravity and magnetic response, these are:

• Calculate Anomalies- The default, this simply calculates the gravity and magnetic anomalies for the current history.
  
• Calculate Block & Anomalies This calculates the current anomaly patterns, but also saves out the geology in an XYZ ASCII block model form. The cube size is defined by the Geophysics Cube Size parameter.
  
• Calculate Anomalies From Block- This calculates the anomaly patterns for a given block model read in from file, and allows in principal the importing of models from other packages.

The results of these calculations will be displayed automatically on completion as raster or contour images.
