%% Display a Sequence Logo for Aligned Amino Acid Sequences % This example shows how to display a sequence logo for a set of aligned % amino acid sequences. % Copyright 2015 The MathWorks, Inc. %% % Create a series of aligned amino acid sequences. S2 = {'LSGGQRQRVAIARALAL',... 'LSGGEKQRVAIARALMN',... 'LSGGQIQRVLLARALAA',... 'LSGGERRRLEIACVLAL',... 'FSGGEKKKNELWQMLAL',... 'LSGGERRRLEIACVLAL'}; %% % Display the sequence logo, specifying an amino acid sequence and limiting % the logo to sequence positions 2 through 10. seqlogo(S2, 'alphabet', 'aa', 'startAt', 2, 'endAt', 10)
