Navigation

To access the information about the available applications, click the 'Applications' tab in the portal main menu. This takes you to the view containing all available applications list along with short descriptions and options for selecting and filtering them. This view is described in detail in the next section. An alternative way, to learn about an application, is to start from creating it in workspace and navigate to its description from there - this is described in the last section of this page.

Note, that the list of available application is always available, whereas, using the applications (adding them to workspace and running) is available only to registered users.

Figure 1. Some of the applications available in IS-EPOS Platform.

In general, Applications in IS-EPOS are divided into several categories comprising tools for data handling, data processing, scientific analysis and visualization. Scientific analysis applications sustain advanced methodologies for AH data analysis, whereas data handling and processing applications comprise tools for data transformation, preparation, filtering, format conversion and basic data processing. The . More detailed category names provide insight on the general purpose of the applications inside each category. The current taxonomy of the IS-EPOS Applications is the following.

Alternatively the user may browse an Episode, upload the data he/she wishes to use for analysis to the personal workspace, and then use these data for visualization, data processing application or data handling application (see figures below).

Step 1:Browse Anthropogenic Hazard Episodes by clicking on "AH Episodes" and select a specific Episode from the list by clicking on one of the panels (e.g. the one indicated by the red box in Figure 2):

Step 2: Select a data type from the list (e.g. catalog in the example shown in Figure 3). There are several data types available with respect to the episode and the induced seismicity technology:

Step 3: Once the User selects one data type he obtains access to data attributes, numerical values and visualization applications. For further data processing the User has to click on the 'Actions' tab and then on the 'ADD TO WORKSPACE' window which appear right below (red frame at the top of Figure 4):

Alternatively, the User may continue from step 2, through the following process:

Step 3b: After selecting an episode the user may receive access to all available data from any episode by clicking on the 'All data related to this episode' tab (Field 4, in the bottom left corner of Figure 5).

Figure 5. Alternative way to add a file to user workspace. 'All data related to this episode' can be used.

Step 3c: A Data search screen is now displayed (See also 'Advanced Data Search' in 'AH Episodes' chapter). The User may either select one or more (even all) episodes, or apply a filter from the list provided such as time range, country, data type etc (Figure 6). All data after the filtering criteria application is now demonstrated and the User may select one or more data types for further processing. If the User chooses the "View File" tab, the same screen as in the previous step, appears. If the User clicks at the 'Add to Workspace' tab (3rd column in the blue panel in Figure 6), the data is directly transferred to his/hers personal workspace. (See also AH Episodes chapter)

Step 3d: Once the selected data are uploaded at the personal workspace, the User may click on the 'Actions' tab in order to use these data in one of the available applications, grouped into 2 categories: 'USE IN APPLICATION' and  'USE IN VISUALIZATION'. This is the Data Oriented Approach shown in Figure 7.

Alternatively, an Application Oriented Approach can be followed as displayed in Figure 8. The User selects the Application first and then clicks on the 'Change input' tab for choosing (Shown in the red frame of Figure 9) the appropriate input data file(s).

available Applications, along with detailed user guides for each service is available in Application User Guides section of this documentation. Apart from categories, each application is described with several keywords characteristic to its functionality. 

Name of the category and keywords might be used for filtering the available applications list (filtering by categories - Field 3, Figure 1, filtering by keywords - Field 2, Figure 1). Full text search is also available to find a required application based on words that might have been used to describe it (Field 1, Figure 1). Information on each application is shown on the screen (short description, category and last update) and the user may upload the Application to the workspace to run it by clicking on the 'Add to Workspace'¹ tab (Field 4,Figure 1). By clicking at the name of each application you are taken to a view containing more detailed information about the chosen application (see the next section).

Application details view

The detailed view of the application (Figure 2 contains a description of the method used for its implementation, description of its parameters and execution characteristics as well as other properties like author, licence (if the application code is available for download), references etc. Among the references, most applications provide links to their user guides, scientific articles related to them (Document Repository) and code repository (if the code is available for download).

This view also allows you to add the application to workspace ('Add to Workspace' button¹)

Running an application

Prerequisites: to be able to run applications, you will have to learn how to add data to workspace - for these, see the AH Episodes guide, you can also find helpful additional information about the workspace itself contained in the  My Workspace guide.

The applications are in fact programs that are run on the computing infrastructure connected to IS-EPOS Platform. They have to be configured with input files, parameters before running, and they produce output files as result. Each application can be run a number of times with different parameters. The user might also have multiple copies of an application, in this way, allowing the user to compare results of running the same code with different parameters or input files. For the purpose of storage and configuration, the application has to be added to workspace¹ - this can be done either from the application list view or application details view (see previous sections), or by using some of the data already existing in your workspace (Figure 3.1)².

See also Usage Scenario section for a full sequence of steps leading to running an application.

A sample view of an application added to workspace is presented in Figure 3.2. If we added the application with the "Use in application..." menu (Figure 3.1), at least one of the input files is already filled. Otherwise, we have to select a file (using the button marked in red in Figure 3.2).  Each input file entry has an information about the file type and number of required files. The selection is restricted only to files have the required type, therefore, you will not be able to choose any file that will be incompatible with this application. Below the input files, the application parameters are displayed.

The application can run with the "Run" button. At this moment, both, the input files and parameters are validated, therefore, if you forgot to add any file or any of the parameters is specified incorrectly (e.g. is outside of the allowed range), you would be informed about it with messages displayed in red color. Once the application is run, its status changes (a detailed description of possible statuses is described in Table 3.1) and it can no longer be run again till the execution finishes. You can interrupt the execution by clicking the "Abort" button.
