No ugly and inefficient loop is required:
>> C = {'Tcgh','A6','1214'};
>> out = sprintf('-%s',C{:});
>> out(2:end)
ans =
Tcgh-A6-1214

@chocho: I am happy to help you but I cannot load data from a screenshot. A screenshot is useless for giving me data. Do you want to me to waste my time by trying to replicate your data arrays? If you actually want help then please upload your data.

>> out = cellfun(@(c)sprintf('%s-%s-%s',c{:}),InterN,'Uni',0)
out =
'TCGA-A6-2677'
'TCGA-AA-3516'
'TCGA-AA-3520'
'TCGA-AA-3521'
'TCGA-AA-3522'
'TCGA-AA-3524'
'TCGA-AA-3525'
'TCGA-AA-3527'
... etc
And look how quickly I could actually help you, once you gave your data. The more you help us, the easier we can help you.

res = strCell{1};
for k=2:length(strCell),
res=[res '-' strCell{k}];
end;
disp(res);

This expands the output res on each iteration, which is not efficient:
See my answer for a simpler and more efficient solution that does not use a loop.
