Difference: NmrDipep (2 vs. 3)

function s2 =  dipep(seq)
% Sequence analysis for didpeptides in a specific sequence.
% Used fields required 
%       s.Sequence -- the sequence typically in a single letter form
%   optional
%       s.Start -- sequence number of first aa in s.Sequence
%       s.Good -- aa's to be favored in id'ing dipeptides
%       s.Bad   -- aa's to be deprecated in id'ing dipeptides

% output
% dipep is a text table in a 50 col setting with vertially arranged fields
% --
% 1 n
% 0 n
% 2 n - number of residue
% s a - amino acid single letter code
% v b - subsequent aa
% 1 f - numer of times ( <=9) that this dipeptide occurs
% * * - starred if f == 1 and not bad (see later)
% 1 s - score of 0 (blank) 1 or 2 for accpetable of good, - for any bad
% e.g.
% input structure  =
%
%     Sequence: 'lagvlgvacwym'
%         Good: 'lvw'
%          Bad: 'ac'
