Number of Released PDB Structures per Year
- X-ray: X-RAY DIFFRACTION, FIBER DIFFRACTION, or POWDER DIFFRACTION
- NMR: SOLUTION NMR or SOLID-STATE NMR
- EM: ELECTRON MICROSCOPY or ELECTRON CRYSTALLOGRAPHY or ELECTRON TOMOGRAPH
- MULTIPLE METHODS: Multiple experimental methods. For example, if a structure is solved by X-RAY DIFFRACTION AND NEUTRON DIFFRACTION, it will be counted only in this category.
