Hi,
I have both backbone NOE and sidechain NOE data for a small protein. When I specify the backbone NOE data during Abinito simulation it works fine with scoring penalties displayed in atom_pair_constraints column. But when I modify the constraints file for sidechains and supply it Relax or Score with “-constraints” flag it doesn’t seem to make any change in the energies, I seriously doubt that It takes those constraints into account during relax. So my questions are:
1. Can relax take sidechain restraints?
2. Is there any special flag to supply during relax?
3. Is there a different format for supplying NOE restraints during relax?Thanks,

What flaq are you using?
-constraints is an option grouping, and shouldn’t work for any protocol.
-constraints:cst_file is for *centroid* mode constraints, so would work with (certain stages of) abinitio, but wouldn’t work with full atom protocols like relax or (full atom mode) scoring.
-constraints:cst_fa_file is the option you’d want to use for full atom protocols like relax.

Thank you very much for the magic flag option.
