Here is the sequence logo predicted by the SAM server.
H = helix
E = sheet
C = loop (or coil)
The taller the letter at each position, the higher the probability of that specific secondary structure for that amino acid.
For example, the amino acid Leucine at residue 21 is highly predicted to be part of a helix. However, the Leucine at residue 29 is predicted to have an equal probability of being anything.
