There are 21 parameters defining which plots are required, one for each of the 21 plots:-
a. Geometry plots -------------- Y <- 1. Ramachandran plot (Y/N)? Y <- 2. Gly & Pro Ramachandran plots (Y/N)? N <- 3. Chi1-Chi2 plots (Y/N)? N <- 4. Residue Phi torsion angle plots (Y/N)? N <- 5. Residue Psi torsion angle plots (Y/N)? Y <- 6. Residue Chi-1 plots (Y/N)? Y <- 7. Residue Chi-2 plots (Y/N)? Y <- 8. Residue Ramachandran plots (Y/N)? N <- 9. Residue chi1-chi2 plots (Y/N)? Y <- 10. Ensemble geometry (Y/N)? Y <- 11. Equivalent resolution (Y/N)? Y <- 12. Model-by-model secondary structures (Y/N)? b. Restraint analyses ------------------ Y <- 13. Distance restraints plot (Y/N)? Y <- 14. Restraint differences plot (Y/N)? Y <- 15. Numbers of distance restraints (Y/N)? Y <- 16. Actual distance - restraint summary (Y/N)? Y <- 17. Violation frequency summary (Y/N)? Y <- 18. Restraint statistics (Y/N)? N <- 19. Restraint spans (Y/N)? Y <- 20. Residue-by-residue restraint violations (Y/N)? Y <- 21. Model-by-model violations (Y/N)?
Note that the default setting for some of the less commonly-used plots is N.
