The packaging of DNA inside a nucleus shows complex structure stabilized by a 
host of DNA-bound factors. Both the distribution of these factors and the 
contacts between different genomic locations of the DNA can now be measured on a 
genome-wide scale. This has advanced the development of models aimed at 
predicting the conformation of DNA given only the locations of bound factors-the 
chromatin folding problem. Here we present a maximum-entropy model that is able 
to predict a contact map representation of structure given a sequence of bound 
factors. Non-local effects due to the sequence neighborhood around contacting 
sites are found to be important for making accurate predictions. Lastly, we show 
that the model can be used to infer a sequence of bound factors given only a 
measurement of structure. This opens up the possibility for efficiently 
predicting sequence regions that may play a role in generating cell-type 
specific structural differences.
