Step by Step
This applications extracts seed files and event files from a selected catalog into the User workspace. These extracted files can be used later on at any application dealing with waveform processing, including 'Spectral Analysis', 'Source Location', 'Moment Tensor Inversion' and 'Seed converter'. ThisThe application uses catalog file (uploaded from the episode data) as an input and allows the User to extract seed, miniSEED and event files. This is an alternative way of exporting seed files instead of searching into the episode database.
The User needs first to select a catalog from the workspace and click subsequently on 'ACTIONS', 'USE IN APPLICATION' andF rom the 'Actions' tab within the Catalog file view, the User may select 'Use in Application' option and then choose 'Signal download tool'
tabs, as indicated by the red boxes in Figure.

SelectionInput of the application
from the data uploaded in the workspace2. After this step, the list of events appears in the screen as shown in Figure 2 and the User is requested to select an event for extracting event information and seed file. The User may also chose downloading
"Signal download tool".
After clicking on 'SELECT EVENTS FROM CATALOG' (red field in Figure 1) the following window appears (Figure 2):

Then, the User may chose which signal types to download between 'Seed Signal', 'Accelerogram Seed Signal', Miniseed Signal' or 'All', by ticking on the respective box shown
at the bottom left corner of Figure 2. Then, the output files are extracted after clicking on the button (green button, bottom Figure 2). Those files are stored in a Signal Download folder, into the User's workspace andin the green field in Figure 1.

Output files can be further used as input in several applications
as mentioned above.Figure 2. Selection of waveform data from the catalog, including ' Spectral Analysis ', ' Localization ', ' Moment Tensor Inversion ' and in all seed or miniSEED converter applications.
