Name

side_projection_match - Do projection matching on a set of class sums representing side views.

Usage

side_projection_match(DataSetName,NumImages,rAngs,SymmetryString,NumLoops=3)

Input

• DataSetName - name of a stack of class sums along with ext.

• rAngs - the set of azimuthal angles to be searched will be [0,rAngs); currently this value will be 360 divided by the order of the axial symmetry. For D3, for example, rAngs, is 120.

• NumImages - the number of images in the stack (and the number of slots to be filled).

• SymmetryString - for example, 'd2', 'c3': must be read by recons3d_4nn.

• NumLoops - the number of rounds of projection matching.

Output

• SPDataSetAngles.txt is a text file with the purported assignment angles.
• SPCurrentVol?.mrc stores the current volume, where ? is an integer
• SPReproj?.spi stores the reprojections
• SPEvenlySpaced.spi gives an even sampling of the projections current volume

Description

Purpose: Do a restricted projection matching on a set of side view class averages. This is to be compared with Sidewinder.

Bugs

Class sums and their rotated/reflected counterparts are entered separately. Better would be to have the program handle this.
