A question about distance restraints

Dear professor,

I used I-TASSER with distance restrains to getting 3D models. I want to explore the cross-linking of protein, so I set the distance of two atom.

The job id number is S459795.
The contact distance restrains were:
DIST 60 CD2 92 NH1 1.5

But the model1 in result was not show right distance. So what's the problem of this situation?

Looking forward to your reply!
Thank you very much!

Yours, Linmei Ren
