Supported data types
The application allows you to modify data files that are in the format of a Matlab catalog (type Data Catalog). This may be a Catalog (a seismic events catalog), Ground Motion Catalog or any other similar type - check other possible catalog data formats, including also catalogs that are produced by joining two different catalog types (products of the Parameters Catalog builder user guide). For the purpose of this guide, we use the seismic catalog (Catalog), but most of the functionality is the same for other types.
Input file specification
The application requires a single file of type Data Catalog (see also the previous section), which is a generic representation of object in a shape of a catalog, for the purpose of this user guide we will use a Catalog (a seismic events catalog).

Filling form values
The application form contains entries for each column present in the input catalog file (marked with (1) in Figure 2). The values might be filled by hand or populated from an event present in the input catalog or from another catalog or event properties file. For the second option, use the Select entry from catalog button (marked with (2) in Figure 2) and choose the event to be modified (Figure 3). To load external event values, use the Load values from file button (marked with (3) in Figure 2) and choose the file from which the event should be loaded (Figure 4) - it might be a file of one the following types: Catalog, Seismic Event (can be obtained as a result of the Signal download tool application) or Extracted relocalized event properties (can be obtained as a result of the Localization application). Note, that if the chosen file is a seismic catalog, you will be also prompted to choose a single event from that file (similarly as in Figure 3).

Depending on the ID specified in the form (marked with (4) in Figure 2), an event will either be modified or added to the input catalog. If the specified ID already exist in the catalog, the event with this ID will be modified by setting the provided values. If the ID didn't already exist in the catalog, a new event with the provided values will be added. Note, that the resulting catalog will be sorted by time, therefore, the event will not be added at the end, but at the right place considering its time. In case of an event modification, if its time changes, it will also be moved within the catalog, to retain the correct sorting.
Apart from setting values for the properties that already exist within the input catalog, we can also add new properties - using the part of the form Add new values (marked with (5) in Figure 2 and demonstrated in Figure 5).

Produced output
The result file will have the same name as the input with additional _mod suffix (e.g., if the input catalog file was called sample_catalog.mat, the result catalog will be named sample_catalog_mod.mat), and it will be visualized within the application outputs.

With the settings presented in Figure 2, the event CZORSZTYN_CIBIS_100010 from the input catalog will be changed, so that its time and magnitude ML is updated. Due to the time change, and the fact that the catalog is always sorted, the event in the resulting catalog was moved after event CZORSZTYN_CIBIS_100011. The comparison of the relevant part of the input and the result catalog is shown in Figure 7 and Figure 8.
