Inter-domain contacts/distances restraints: The Cross-Linking data or contacts/distances restraints should be uploaded in the following format:

7	137	24	0.88
20	165	28	0.93
51	220	29	0.79
63	220	21	0.86
82	169	18	0.96
94	168	17	0.77
110	172	21	0.69
124	187	27	0.91

where the first column is the index of the first CA atom, and the second column is the index of the second CA atom. The third column is the maximum distance of the residue pair. The fourth column is the confidence score that the distance of the residue pair is less than the given distance listed in the third column. It is optional and will be set to 1 if users did not provide. The indexes are for the full-length sequence rather than the individual domain. For example, "7 137 24 0.88" in the first row indicates that the CA distance between the 37-th residue and the 209-th residue has a confidence of 0.88 being less than 24Å.
