I’m trying to dock a large piece of dsDNA (149bp) with a tetramer protein (111 residues as a monomer). Everything works great with it0. It reads in all of the unambiguous restraints, NCS, C2, and ambig restraints. I get good results.
However, every structure in it1 fails with:
EVALUATE: symbol $DIHEDRAL_DELTA set to 141.509 (real)
CNSsolve> restraints dihedral
DIHEDRAL> ! gamma
DIHEDRAL> assign ( segid $segid and resid $resid and name O5’ )
%CSTRAN-ERR: allocation for assignments exceeded
increase NASSignment and run again.
%CSTRAN error encountered: exceeded allocation for assigments
(CNS is in mode: SET ABORT=NORMal END)
ABORT mode will terminate program execution.
Program will stop immediately.
I know that I can limit the amount of restraints but considering where it stopped (dihedrals for the DNA - dna-rna_restraints.def) I think the better solution would be to find NASSignment and increase that value. Can anyone point me in the direction where the variable exists and how to modify it?
