No problem. As usual with GCG, try the "optional parameters" first (look in
the program manual under "optional parameters" at the end of the documentation
for the program you are using, look in GenHelp progname option, or just run
the program with /check to show the command line options).

In this case, SQUIGGLES /SHOWSEQ will put the sequence on the plot. You can
also just show part of the sequence (main stem-loop for example), adjust or
remove the numbering, set the height of the sequence characters, and pivot
parts of the structure to make the plot look better (or to make room for the
sequence characters).

You also have all the standard GCG graphics options to change color, scale,
font, orientation, and so on when preparing graphics for publication.
