X labeling from file

I have a file formatted as follows:

a c g g t c c a

I want to use those characters as labels for a plot. I understand you can use set(gca,'XTickLabel',{var}) to set the axis, but I can't seem to import the data in a way that it can be read. I have tried textread, textscan, csvread (putting commas after ever character), and straight importdata. I can get a 1xn array consisting of those characters, but I can't use them as labels. Error message is:

??? Error using ==> set

Cell array of strings may only contain string and numeric matrices

Any advice?

Thanks

I got it to work using the following:

bars = [0,0,985,62,...] (the data)
num = [1, 2, 3, 4,...] (just integers increasing)
seq = [a,f,c,f,...] (the labels)
plot(bars)
set(gca,'XTick',[num])
set(gca, 'XTickLabel', seq)

labs = textscan(fid, '%s');
set(gca, 'XTickLabel', labs);

That doesn't seem to work. I typed

>> fid = fopen('x.txt');

>> labs = textscan(fid, '%s');

>> set(gca,'XTickLabel',{labs})

also tried

>> fid = fopen('x.txt');

>> labs = textscan(fid, '%s');

>> set(gca, 'XTickLabel', labs)

(using no braces)
