Fig5e_S4a_S4b_S4c_transformation_data.txt

The file transformation.txt contains the angles and translations that describe the rotation of the cell in the optical stretcher. Note that the underlying images are cropped and binned before the coordinates are extracted or calculated. Origin of the data: A single dataset of a fixed and stained cells that is acquired with a beam energy of 13.8keV is processed as described in the materials and methods part to obtain the coordinates of the BaSO4 grains and a description of the movement of the cell in the optical stretcher. How to use: To obtain the the direction of the incident beam calculate (M_y(alpha)*M_x(beta)*M_y(gamma))^(-1) * (1,0,0)^t for every set of angles (alpha, beta, gamma). M_i is the 3D rotation matrix around axis i.
