This code adapts the position, energy and weight of beamlets to keep planned dose levels to patients taking the specific geometry of a given fraction into account.

The code reads a patient directory structure as given by MCAuto-Astroid to get the necessary treatment parameters.

• None at the moment

• To adapt to internal coordinates the CT's coordinates undergo: x ↔ z transformation
• Offsets are internally defined as the distance from the lower left corner (not the center of the voxel) to the isocenter. They are transformed as: x ↔ z, x → -x, offset -= 0.5*voxn*voxd
• Couch angle is reversed and gantry angle is taken as ang = 270-ang
• Positions and directions read from Tramp are transformed as in: x → -y, y → -x
• Same transformation is applied to treatment planes
