From distance map to 3D model

I need to obtain a 3D model of a protein from predicted distances of each pair of amino acids. In the following image you can see this problem.

There are several tools for this purpose, you can see them here (section Structure Calculation). I'm trying to use the tool CYANA. In this web page we can find an explanation in order to understand the NMR data, including the restraints used to obtain the protein structures. This paper proposes an algorithm to determine protein structures from NOESY data. NOESY data is often used in 2D NMR.
