Preventing "missing wedge bias" is an essential step to accomplish this.

This "missing wedge bias" towards favoring larger density overlaps can cause misalignment of subtomograms; however, it can be compensated for by cross correlation map normalization or other methods.

To avoid missing wedge bias, we used cross-correlation map normalization (Schmid and Booth, 2008).
