Computer averaging of 50 S ribosomal subunit electron micrographs.
Micrographs of one of the views of the large Escherichia coli subunit negatively stained with uranyl acetate were computer averaged using two techniques: the maximum-likelihood method and the correlation method. In both cases, extremely similar images were obtained. The same fine structure of the subunit has also been observed using optical averaging.
