Hi All,

I am trying to apply distance constraint between one of my ligand atom and protein atom but it is not working. Here is my script which I am using it. Is it right ?

restraints.RST file

&rst iat=675, 2143,
r1=0.00, r2=2.00, r3=6.00, r4=99.00, rk2=1.0,rk3=1.0,
/


100ps MD relax system (NPT)
 &cntrl
  imin = 0, irest = 1, ntx = 5,
  ntt = 1, tautp = 1.0, tempi = 300.0, temp0 = 300.0,
  ntp = 1, taup = 2.0, pres0 = 1.0,
  ntb = 2, iwrap=1,
  cut = 10, ntr = 0,
  ntc = 2, ntf = 2,
  nstlim = 50000, dt = 0.002,
  ntpr = 1000, ntwx = 1000, ntwr = 1000
  nmropt=1, /
 &wt type='END' /
 DISANG=restraints.RST
 &end

Thanks
Sonu
