7.6 Compare catalogs.

CompiCat allows the user to compare the initial catalog with the reference one and determine their intersection or difference and catalog of equivalent pairs or nonequivalent events. The tool makes use of the definition of equivalent events set up by the user defined Proximity limits.

To open the Compare catalogs tool window click button



The Catalogs tab allows to chose Reference catalog for the comparison with Initial catalog along with the method of this comparison.

Click Browse button, browse the directories on your computer for the reference catalog, and open it.

The two catalogs could be compared by Intersection, Difference, Equivalence, and Nonequivalence.      

  • Intersection mode selects all events from Initial catalog that have equivalent in Reference catalog.

  • Difference mode selects all events from Initial catalog that have no equivalent in Reference catalog.

  • Equivalence mode creates the catalog of groups of equivalent events from Initial catalog and Reference catalog.

  • Nonequivalence mode selects all events from either catalogs that do not appear in groups of equivalent events.

 The resulting catalogs could be Exported in the standard 68-bytes ASCII format. In case of Equivalence and Nonequivalence modes the records from Initial catalog and Reference catalog are marked respectively with 1 and 2 in the field of Intensity (which original content is lost after completion of Compare catalogs).
 


The content of Proximity limits tab window of Compare catalogs tool is the same as of Remove duplicates. By definition, the two events, one from Initial catalog and another one from Reference catalog, are equivalent, if all the differences are less than or equal to the selected values in the five Proximity limits boxes. (Note that CompiCat program presumes no equivalent events in Initial catalog. Therefore, a record from the initial catalog may have several equivalent records in the reference catalog, while a record from the reference catalog may have no more than 1 equivalent in the initial catalog.)

 

The button Apply confirms the choice from the Catalogs and Proximity limits tabs and runs the selected procedure. To rerun Compare catalogs anew without saving the current results the user can change some of the Tool parameters and click the button Apply.
 
The button OK is used to accept all the results of the Tool.
 
The button Cancel is used to cancel all the actions performed by the Tool earlier and closes its window.
 
By clicking the Default button the user sets the default values of the Tool. By clicking the Reset button the user can remove all the changes introduced after entering the Tool window. (Note that Reset button during the first usage of the Tool is equivalent to the default values.)
