Perl script was used to extract particles in boxes of 512 x 512 pixels using the MRC program LABEL, and phase corrected using SPIDER.  After CTF correction, the box size was cropped and sampling reduced so that all images were at 2.8 A per pixel in 196 x 196 pixel boxes.  Images were band-pass filtered between 285 A and 6 A and normalized to zero mean and the same sigma in SPIDER.</details>
