stacker.residue_movement.calc_center_3pts

calc_center_3pts(a, b, c)

Finds the average x, y, z position of three (x, y, z) Vectors.

Takes in three Vectors generated using the pdb.xyz method and finds their center. Works with three points that make up a triangle (like those within a 6-member ring).

Parameters:

aVector

x, y, z coordinates of the first point.

bVector

x, y, z coordinates of the second point.

cVector

x, y, z coordinates of the third point.

Returns:

midpointVector

One Vector with (x, y, z) coordinates at the center of the three input Vectors.
