How to add the results of nmercount

Hi,

I would like to use nmercount to count the 5-mers in multiple strings, and then to add the counts in only one structure.

Is there a quick way of adding 2 nmercount results?

Perhaps the quickest way would be to join the sequences prior to running nmercount, using a character not used in the sequences you are joining.

The following example joins the sequences using "!":

% Get 3 protein sequences and join them with "!" as a delimiter
s1 = getgenpept("AAA59174",'SequenceOnly',true);
s2 = getgenpept("AAC29001",'SequenceOnly',true);
s3 = getgenpept("O00327",'SequenceOnly',true);
sAll = strjoin({s1, s2, s3}, "!");

% Run nmercount and remove rows that contain "!"
nmers = nmercount(sAll,5);
rows2remove = find(contains(nmers(:,1), "!"));
nmers(rows2remove,:) = [];
