Only experimentation will find a suitable result which gives neither too much nor too little detail. Look for symmetry in the lines for foldback regions. Note the use of several colours to show regions of different energetic stability. This will display diagrams of as many suboptimal structures as required. These will influence all the possible folding conformations.
Optional exercise Examine the cucumber mosaic virus-associated satellite RNA sequence.
Note the variety of different structures with very similar theoretical stabilities.
