||Cryoelectron tomography (CET) and Scaling index based segmentation (SIBS)
||"When taking into consideration that the segmented membrane
structure is incomplete due to the missing wedge
(only ~70% of the total cell surface is clearly visualized), [researchers]
estimate that approximately 15% (29/275?100?100/70) of
the ribosomes are membrane-associated in [researchers'] case."
