Data items in the MA_DISTANCE_RESTRAINTS category records the list of distance restraints used in the modeling. These distances can be atomic or residue-wise distances. This has been adapted from the widely used CASP RR format (http://www.predictioncenter.org/casp8/index.cgi?page=format#RR). These distances may be derived from various coevolution MSA or other exeperimental or computational methods.
