Member Function Documentation

get_desc()

string EMAN::SNREvalProcessor::get_desc ( ) const

inlinevirtual

Get the descrition of this specific processor.

This function must be overwritten by a subclass.

Returns

The description of this processor.

Implements EMAN::Processor.

Definition at line 486 of file processor.h.

                {
                        return "Evaluates the SNR of the particle using a masking method similar to that used in the CTF analysis process. The image is not changed. The resulting value is placed in the particle dictionary as eval_maskedsnr";
                }

get_name()

string EMAN::SNREvalProcessor::get_name ( ) const

inlinevirtual

Get the processor's name.

Each processor is identified by a unique name.

Returns

The processor's name.

Implements EMAN::Processor.

Definition at line 458 of file processor.h.

                {
                        return NAME;
                }

References NAME.

get_param_types()

TypeDict EMAN::SNREvalProcessor::get_param_types ( ) const

inlinevirtual

Get processor parameter information in a dictionary.

Each parameter has one record in the dictionary. Each record contains its name, data-type, and description.

Returns

A dictionary containing the parameter info.

Reimplemented from EMAN::Processor.

Definition at line 473 of file processor.h.

                {
                        TypeDict d;
//                      d.put("sum", EMObject::EMDATA, "Adds the weights to sum for normalization");
//                      d.put("sqrt", EMObject::INT, "Weights using sqrt of the amplitude if set");
                        return d;
                }

NEW()

static Processor * EMAN::SNREvalProcessor::NEW ( )

inlinestatic

Definition at line 481 of file processor.h.

                {
                        return new SNREvalProcessor();
                }

process_inplace()

void SNREvalProcessor::process_inplace ( EMData *  image )

virtual

To process an image in-place.

For those processors which can only be processed out-of-place, override this function to just print out some error message to remind user call the out-of-place version.

Parameters

image

The image to be processed.

Implements EMAN::Processor.

Definition at line 1218 of file processor.cpp.

}

set_params()

void EMAN::SNREvalProcessor::set_params ( const Dict &  new_params )

inlinevirtual

Set the processor parameters using a key/value dictionary.

Parameters

new_params

A dictionary containing the new parameters.
