rotate_ss − rotate or mirror coordinates of secondary structure plot
rotate_ss.pl [−a angle] [−m] old_ss.ps > new_ss.ps
rotate_ss reads a PostScript RNA secondary structure plot, as produced by RNAfold or RNAplot, rotates and/or mirrors the coordinates, and writes the new plot to STDOUT.
Rotate the plot counter-clockwise by angle degrees.
Mirror the coordinates in the plot, i.e. convert from a couter-clockwise to clockwise layout. Note that, if both −m and −a are given, the plot is first mirrored, then rotated.
