Chirality2D

class Chirality2D : public feasst::Analyze

Compute the 2D chirality by analyzing the sign of the cross product between two bonds.

Arguments

• group: group index in Configuration (default: 0).

• bond1: index of the first bond (default: 0).

• bond2: index of the second bond (default: 1).

• sign_error: error if chirality of sign and != 0 (default 0).

• Stepper arguments.
