static float IMP::em::CoarseConvolution::convolution ( const DensityMap em_map,
DensityMap model_map,

bool  recalc_ccnormfac = true 
)
static

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

Note
This is not the local CC function
Parameters
[in]em_mapthe target map (experimentally determined)
[in]model_mapthe sampled density map of the model
[in]voxel_data_thresholdvoxels with value lower than threshold in model_map are not summed (avoid calculating correlation on voxels below the threshold)
[in]recalc_ccnormfacIgnored. The purpose is to determines whether the model_map should be normalized prior to the correlation calculation. false is faster, but potentially inaccurate
Returns
the convolution value between two density maps
Note
recalc_ccnormfac is ignored.
