Cross correlation coefficient between the em density and the density of a model. moddens threshold can be specified that is checked in moddens to reduce elements of summation
[in] | em_map | the target map (experimentally determined) |
[in] | model_map | the sampled density map of the model |
[in] | voxel_data_threshold | voxels with value lower than threshold in model_map are not summed (avoid calculating correlation on voxels below the threshold) |
[in] | recalc_ccnormfac | Ignored. The purpose is to determines whether the model_map should be normalized prior to the correlation calculation. false is faster, but potentially inaccurate |
