A GUI-based intuitive tool for analyzing formats and extracting contents of binary data in fusion research

• A GUI-based intuitive tool for data format analysis is presented.
• Data can be viewed in any data types specified by the user in real time.
• Analyzed formats are saved and reused as templates for other data of the same forms.
• Users can easily extract contents in any forms by writing a simple script file.
• The tool would be useful for exchanging data in collaborative fusion researches.

An intuitive tool with graphical user interface (GUI) for analyzing formats and extracting contents of binary data in fusion research is presented. Users can examine structures of binary data at arbitrary addresses by selecting their type from a list of radio buttons in the data inspection window and checking their representations instantly on the computer screen. The result of analysis is saved in a file which contains the information such as name, data type, start address, and array size of the data. If the array size of some data depends on others that appear prior to the former and if the users specify their relation in the inspection window, the resultant file can also be used as a format template for the same series of data. By writing a simple script, the users can extract the contents of data either to a text or binary file in the format of their preference. As a real-life example, the tool is applied to the MHD equilibrium data at JT-60U, where poloidal flux data are extracted and converted to a format suitable for contour plotting in other data visualization program. The tool would be useful in collaborative fusion researches for exchanging relatively small-size data, which don’t fit in well with the standard routine processes.
