6CYANA: structures secondary - CYANA command

Parameters: structures=<integer>               (default: 1)
            mode=classic|normal|simple|ovw|sep (default: normal)

mode=owv or mode=sep will produce overviews over all of the following
secondary structure elements: alpha helices; 3,10 helices; pi helices;
and beta sheets. With mode=sep the overview will contain one table of
helices and one of sheets; with mode=ovw all secondary structure
elements will be listed in the order in which they occur in the residue
sequence.

The following terms may be used (mode=ovw|sep):
   ap   : current strand anti parallel to previous strand
   p    : current strand parallel to previous strand
   ud.  : undefined; check with a detailed secondary structure
          view (e.g. mode=normal)

In case a bifurcated sheet is encountered, the sheet will be listed
twice in case mode=sep is used. The second time its data are output
both the sheet identifier and the first strand will differ from what
was given before.
