OPERA may be used very quickly via its GUI facilitating context elaboration and results exploitation. No code knowledge is necessary. It is also possible to use it in batch mode via a shell and especially on grid computers with no display properties. On the other hand, it is also possible to use it via its Java interface inside a higher level tool.
So, two jar files are available:
- opera-NN.n-jar-with-dependencies.jar : executable jar including all needed libraries => it is the file to use for GUI utilization but it may also be used for the Java interface
- opera-NN.n.jar : includes only OPERA classes => to be used for Java interface, under the condition of linking with the right version of called libraries as GENOPUS orPATRIUS (see Dependencies page)
The GUI mode
- Overall presentation: basic properties
- Operaapp configuration file: description of the configuration file
- Configuration panel: which kind of computtaion to use and Norad Ids selection
- Solar activity panel: which solar activity to take into account
- Parameters panel: changing by default computtion parameters
- Console panel: synthetic results display
- Result files: description of the xlsx/csv output files (since V7.2.2).
- Plots panel: description of available plots (since V7.2.2)
