Variogram Control File
A Variogram Control File can be saved on the Chart toolbar once a semi variogram map or chart has been calculated, and provides a way of passing variogram information between Stats | Semi Variogram Map, Stats | Semi Variograms, and any function that need to reference a semi variogram as part of its modelling parameters.
Double-click (or click on the Select icon) to select the name of the Input variogram control file that contains the directions you want to load.
You can right-click in the File box to view the contents of the file. All conceivable orientation conventions are listed.
