Constructor.
hier | The root hierarchy for applying the restraint |
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 |
micrographs_number | Number of micrograph particles that were used to generate the class averages, if known |
n_components | Number of the largest components to be considered for the EM image |
