PROCHECK Operating Manual

3. Input requirements

The only input required for PROCHECK is the PDB file (Bernstein et al., 1977) holding the coordinates of the structure of interest.

For NMR structures, each model in the ensemble should be separated by the correct MODEL and ENDMDL records (see Appendix B: Brookhaven PDB file format). Only the first model will be analysed. A separate program, PROCHECK-NMR deals specifically with the analysis of NMR structures.
