make3dreal

This program builds a 3d model from a set of projections (class averages) using unfiltered back-projection

make3dreal <input file> [out=<outfile>] [noweight] [sym=<c4,icos,etc>] [mask=<rad>] [fftmerge=<fftmodel>]

Parameters:


<input file>File containing class averages
[out=<outfile>]Output 3D MRC file
[noweight]Normally the class averages are weighted by the number of raw particles used, this disables that
[sym=<c4,icos,etc>]The symmetry to apply to the model
[mask=<rad>]real-space mask radius
[fftmerge=<fftmodel>]Fourier model to merge with real model

Usage:

make3dreal classes.1.img out=threed.1.mrc sym=c4 mask=42

Description

This program is used to build a 3d model from a set of projections/class averages. The individual projections must already have assigned euler angles in their headers. This program builds a model using unfiltered back-projection. It is intended to be combined with a Fourier model, or some other filtering technique.

'sym=' specifies the symmetry of the 3d model. If nothing is specified, the model is assumed to have no symmetry. Currently, only Cn, Dn, oct and icos symmetries are supported.
