Try this:

data = readmatrix(fileName, 'NumHeaderLines', 5)

@Mr Thadi Why? Why do you want to mess with the complications of cell arrays, fopen, strcmp, etc. when you don't have to??? Why not do it like I said, or with the modification @Voss suggested about tossing out any rows with 1 or more nans in them? Voss's suggestion would be
fileName = "radio.txt";
data = readmatrix(fileName, 'NumHeaderLines', 5)
% Throw out any rows that have a nan in them.
badRows = any(isnan(data), 2);
data = data(~badRows, :);
% Sum up each column over all the rows in that column.
columnSums = sum(data, 1);
bar(columnSums);
grid on;
