Description

Defines a fragment to be analyzed by a subsequent grid search. The angle selection must select a connected subset of the torsion angles. Alternatively, the option none can be given to undefine the current fragment.

 grid fragment "PSI 7 + PHI PSI CHI1 8 + PHI 9"

defines a molecular fragment comprising the ψ angle of residue 7, the ψ, φ and χ1 angles of residue 8, and the φ angle of residue 9.
