sel bonds


Restrain a set of two bonds to be triangular with the provided parameters

d1 d2 angle [esd=0.02]

For a given set of bond pairs, sharing an atom or atom triplet generates two DFIX commands and one DANG command.

>>tria 1 1 180 C1 C2 C3 will generate DFIX 1 0.02 C1 C2 C2 C3. \par >>DANG 2 0.04 C1 C3 will calculate the distance for DANG from d1 d2 and the angle.
