I assume that there is a tiny number of people, who know directly what "Maros and Mezaros test problem" is and how the .SIF format is defined. It is unclear, what you have posted in your comment and you cannot expect us to guess, what it means. I suggest to provide a meaningful and clear description of the file format. Most likely the authors you mention are professionals in this topic, such that you should explain, what they answered to your question.
