Hi I went to the rcsb, then click on advanced search, then specified the experimental method="neutron diffraction" and has experimental data=y (this is not clear to me if this is for neutron diffraction data or only x-ray diffraction data?). Got 178 structures... but if I click on 3dview-> density enable I get always an error saying "error enabling"... (At least for the top ~25 most recent structures with the brave-browser and firefox on a ubuntu 20.04.3 machine.. so maybe the problem is at my end?) ccp4mg loads fine all the structures and maps where the structure was solved by both methods...
