Detailed Description

Tries to mask out only interesting density.

Parameters:

	au	The asymmetric unit to mask, if -1 masks all asymmetric units but assigns each a unique value

void AutoMaskAsymUnit::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.

virtual string EMAN::AutoMaskAsymUnit::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.

virtual TypeDict EMAN::AutoMaskAsymUnit::get_param_types

(
