After the User adds the Application into his/her personal workspace, the following window appear on the screen (Figure 1):
Figure 1. Input window of the "Test for Multimodal Magnitude Distribution" application.
The User shall click on 'SELECT FILES' button in order to use seismic catalog data among the ones that are already uploaded in his/her personal workspace.
The User is then requested to fill in the fields shown below:
The default values and the possible range of the inputs are provided by the application as shown in the example of Figure 1.
After defining the aforementioned parameters, the user shall click on the 'RUN' button and the calculations are performed. The Status changes from 'Submitting' through 'Queued', than 'Running' and finally 'Finished'. The output is created and plotted in the main window just below 'RUN' button. The Analysis Results table appear on the screen and comprise 3 individual outputs:
A) multi_modality_chart_data.mat: This output includes 3 figures (e.g. the one shown in figure 2). The first figure shows the Probability Density Function (pdf) of Magnitudes for h=h_critical (Figure 2). The second and third figures show the 1st and 2nd derivatives of the aforementioned magnitude pdf. The location of the extremum and inflection points are also indicated in the plot. The figures can be downloaded in different formats (e.g. *.jpg, *png).
Figure 2. Sample output figure (Magnitude PDF) generated by the Application.
B) multi_modality_report_data.mat: This is a matlab file with the results of the application (figure 3). Note that for the last 2 parameters (p-values), when their value is less than 0.05, then the corresponding null hypothesis can be rejected at 0.05 significance.

C) Report_Multimodality.txt: This is an ASCII file with a summary of the input parameters and results (Figure 4).
