- etspy.align.calc_shifts_cl(stack: TomoStack, cl_ref_index: int | None, cl_resolution: float, cl_div_factor: int) ndarray[source]
Calculate shifts using the common line method.
Used to align stack in dimension parallel to the tilt axis
- Parameters:¶
- stack: TomoStack¶
The stack on which to calculate shifts
- cl_ref_index: int | None¶
Tilt index of reference projection. If not provided the projection closest to the middle of the stack will be chosen.
- cl_resolution: float¶
Degree of sub-pixel analysis
- cl_div_factor: int¶
Factor used to determine number of iterations of alignment.
- Returns:¶
yshifts – Shifts parallel to tilt axis for each projection
- Return type:¶
