How to interpret your output.

each file indicates which prediction method it is from (rf or dca) and the sequence separation for rf (6, 12, 24).
Sequence separation is the distance between residue pairs in the sequence. More details available in our paper at 
https://bmcbioinformatics.biomedcentral.com/articles/10.1186/s12859-019-2627-6

Each line in the output files will look something like this:
10  19  0  8  0.834 T0856

1st number = residue 1
2nd number = residue 2
3rd and 4th number = d1 and d2 from CASP format (legacy format requirement. not relevant to predictions here)
5th number = your prediction! A probability (between 0 and 1) that the residues are in contact. With 0 = no contact and 1 = contact
6th item (if present) = target name of your input if available. (absent in dca map file)
