Width distribution of L-type BSE fibrils.
(A) A sample electron micrograph and histogram of the maximum width of 231 two-protofilament L-type BSE fibrils. (B) A sample electron micrograph and histogram of the maximum width of 636 one-protofilament L-type BSE fibrils. The width measurements were performed using EMAN’s boxer program.
