After obtaining a Kriging result in the current iteration, the next step is to compare it with a Kriging result from the previous iteration (see the overall workflow). Remember that the difference between the current iteration and the previous one is the current sample set, which is contained in the current iteration but not in the previous one. To compare Kriging results, click the 'Compare to previous Kriging result' menu item under the 'Geoprocessing' menu. In the popped-up dialog, first select a previous iteration (i.e. a sample set combination) in the top drop-down list, then select a dose version for the iteration (i.e. a combination of dose versions for all contained sample sets) in the bottom drop-down list.
