Get the descrition of this specific processor. This function must be overwritten by a subclass.
Reimplemented from EMAN::CircularMaskProcessor. Definition at line 2372 of file processor.h. 02373 { 02374 return "a gaussian falloff to zero, radius is the 1/e of the width. If inner_radius>0, then \ 02375 outer radius specifies width of Gaussian starting at inner_radius rather than total radius."; 02376 }

|
Get the processor's name. Each processor is identified by a unique name.
Implements EMAN::Processor. Definition at line 2347 of file processor.h. 02348 {
