Constructor & Destructor Documentation

def IMP.pmi.restraints.em2d.ElectronMicroscopy2D_FFT.__init__ (   self,
  hier,
  images = None,
  pixel_size = None,
  image_resolution = None,
  projection_number = None,
  resolution = None 
)

Constructor.

Parameters
hierThe root hierarchy for applying the restraint
imagesSPIDER FORMAT images (format conversion should be done through EM2EM)
pixel_sizesampling rate of the available EM images (angstroms)
image_resolutionresolution at which you want to generate the projections of the model. In principle you want "perfect" projections, so use the highest resolution
projection_numberNumber of projections of the model (coarse registration) to estimate the registration parameters
resolutionWhich level of model representation to use in the fit
n_componentsNumber of the largest components to be considered for the EM image
