The question: "I am trying to plot symmetry related objects (a lattice) using oplot. When I run the following macro:

  plot_setup temp ; ; ;
  plot_on
  mol r8 ca ; end
  centre_id term_id r8 1123 ca ;
  symm_setup r8 61.28 76.83 57.78 90 90 90 p212121
  symm_object r8 sym 30
  plot_off

I get the correct picture up on the terminal (18 symmetry objects). When I run the output file through oplot or ODLEDIT/OPLOT, however, only a single pair of objects related by a 180 degree rotation appears in the Postscript file. Using the simple Plot command also does not seem to work."

Markku Saarinen replied: "I was trying to do the same, asked help from Morten & after that from Alwyn. Different explanations why it does not work. Finally Alwyn suggested the use of 'symm_sphere' instead. This command gives you each SYM_x as a molecule, which you can treat any way you like. Try plot on those."

Morten followed up: "I cannot reproduce this error, and I couldn't reproduce Markku's error either. What you are doing is correct, I can't explain why it doesn't work. Do you have the latest version of oplot? Check with oplot -r, it should say version 1.15. If not, get the latest version from the server. (Ignore messages saying "No open object")."
