Mark, Justin,

Thanks for advises. Indeed I think that simple text editor would be better sollution in my casw because of small number of restraints.

I just have a question about definition of the Distances

This is the default of the restraints between atom 10 and 16.

[ distance_restraints ]
; ai aj type index type’ low up1 up2 fac
  10 16 1    0     1     0.0 0.3 0.4 1.0



I'd like to restrict distance between both of that atoms 7.96 < r(Ca-Ca)< 8.41

I've found that the up1 is the 7.96 and up2 is the 8.41 but how I could specify 'low' in the above table ? Should I obtain value for the initial Ca-Ca distance between my residues from the initial structure? How I could do it?


See Figure 4.13 and equations 4.79 in the manual.  r0 = low, r1 = up1, and r2 = 
up2.
