Get the descrition of this specific processor. This function must be overwritten by a subclass.
Reimplemented from EMAN::CircularMaskProcessor. Definition at line 2551 of file processor.h. 02552 { 02553 return "a gaussian falloff to zero, radius is the 1/e of the width. If inner_radius>0, then \ 02554 outer radius specifies width of Gaussian starting at inner_radius rather than total radius."; 02555 }

|
Get the processor's name. Each processor is identified by a unique name.
