static float IMP::em::CoarseConvolution::convolution ( const DensityMap *  em_map, DensityMap *  model_map, float  voxel_data_threshold, 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_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 wheather the model_map should be normalized prior to the correlation calculation. false is faster, but potentially innacurate

Returns:

the convolution value between two density maps

Note:

recalc_ccnormfac is ignored.
