NMRWish Built-In TCL Functions
dynGetOmega: Get the Omega torsion angle CA(i-1) C(i-1) N(i) CA(i) from selected residues.

Flag Argument Default Description  -src ptrVal Source of Structure Data.  -res resList Residue ID List.  -chain cName Chain Name.  -seg sName Seg Name.  -round rVal Round Angles to Nearest rVal. Notes:   1. Omega(i) Torsion is Defined as: CA(i-1) C(i-1) N(i) CA(i)   2. Returns values adjusted to range -180 to 180.
