Results in CAPRI are passed from one work step to another via files generated by GAMS programs, mostly in GDX format. The GDX format is a binary file format specific to the GAMS language. It cannot be opened with a normal text editor or a program as Microsoft Word but requires a specific Application Programming Interface (API). That interface is integrated in the the CAPRI GUI to access results from the different work step, but also to offer an own GDX viewer which the name look and feel as the CAPRI exploitation tools. Alternatively, the GAMS IDE may be used to open GDX files.
In a first step, use the "Load gdx file" button to open a GDX file via a file selection dialogue. Later, additional files may be added. If the file can be loaded, a table will be shown which shows the different GAMS symbols found in the GDX file.:
Next, select the symbol you would like to view by selecting the appropriate row in the table with a mouse click. Only the first selected symbol from each table will be loaded.
Repeat the two steps to load additional symbols from the same or different files. Then, press the "Load selected table(s)" button.
The major results sets from the work steps can be viewed by using the "show results" button in the related work step. Using the GDX file viewer is therefore typically only necessary for some files of more technical content, or when analyzing output of GAMS programs not in the normal CAPRI production chain.
