void create_radial_func (vector< float > &radial_mask, EMData *image) const

Detailed Description

Sets the structure factor based on a 1D s/intensity curve as an XYData object.

Parameters:
strucfac XYData object with the curve to be imposed as intensity as a function of s
apix A/pix value. Overrides and replaces apix_x/y/z in image

virtual string EMAN::SetSFProcessor::get_name (  )  const [inline, virtual]

Get the processor's name.

Each processor is identified by a unique name.

Returns:
The processor's name.

Implements EMAN::Processor.
