FORM CONTROL FOR SEQUENCE LOGOS

   FORM CONTROL FOR SEQUENCE LOGOS
   controlled by parameter formcontrol

   Normal logo (normallogo):
   Note: the sine wavelength is 3.6 amino acids, corresponding to an alpha helix.
   

   Variable logo (varlogo):
   Plot Hmax instead of R(l).
   

   Equal logo (equallogo):
   Equal stack heights. Note that sequence conservation data is lost.
   

   Rare logo: (rarelogo):
   Plot 1-Pi instead of Pi.  Normal stack heights
   

   Rare-Equal logo: (rareequallogo):
   Plot 1-Pi instead of Pi, equal stack heights.
