Computes the cross product of two vectors in three-dimensional euclidean space.
Usage
xprod(...)
Arguments
...
vectors involved in the cross product.
Value
This function returns a vector that is orthogonal to the plane containing the two vector used as arguments.
Details
For each methionyl residue taking place in a S-aromatic motif, this function computes the aromatic residue involved, the distance between the delta sulfur and the aromatic ring's centroid, as well as the angle between the sulfur-aromatic vector and the normal vector of the plane containing the aromatic ring.
