Constructor & Destructor Documentation

def IMP.pmi.restraints.em2d.ElectronMicroscopy2D.__init__	(		self,
			representation = None,

			image_resolution = None,
			projection_number = None,

Constructor.

Parameters

representation	DEPRECATED, pass 'hier' instead
images	2D class average filenames in PGM text format
pixel_size	Pixel size in angstroms
image_resolution	Estimated resolution of the images in angstroms
projection_number	Number of projections of the model to generate and fit to images. The lower the number, the faster the evaluation, but the lower the accuracy
resolution	Which level of model representation to use in the fit
n_components	Number of the largest components to be considered for the EM image
hier	The root hierarchy for applying the restraint
