ctfavg

Averages a set of 2D images with ctf correction

ctfavg <infile> <outfile> [res=<in A>] [sffile=<file>] [mask=<rad>] [copyeuler] [refmask] [ref0] [copyrefs] [even|odd] [snrmult=<val>] [nolog]

Parameters:


<infile>Set of images to be averaged
<outfile>Output, 1 image will be appended
[res=<in A>]Resolution in A if structure factor is not used
[sffile=<file>]Structure factor file used to fit data in infile
[mask=<rad>]Circular mask
[copyeuler]Used only if the filspec is cls####, will read the Eulers from proj.hed
[refmask]Only for cls#### files, will mask based on proj.hed
[ref0]Will ignore the first image in the file
[copyrefs]Copy proj.hed image into the output file
[even|odd]Uses only even or odd numbered particles
[snrmult=<val>]Multiply the SNR by this number when Wiener filtering
[nolog]Do not log a record of this program in .emanlog

Usage:

ctfavg cls0000.lst classes.hed sffile=groel.xray

Description

This program will average a set of prealigned images with CTF correction.
