== threed_xx == Produced by - '''e2make3d.py''' sometimes postprocessed There are 3 types of 3-D files produced during refinement. * threed_xx - The minimally processed 3-D reconstruction. It is filtered, but not masked or normalized. * threed_filt_xx - This is the masked version of the 3-D reconstruction, and is used as input for the next round of refinement. Based on the mass you provided, 1.0 should be the correct isosurface for viewing, but you will find that this depends a lot on resolution. * threed_mask_xx - This file contains the mask applied to threed_xx. It is a greyscale mask file with values from 0 to 1.0.
