Why does not textscan work with importing this?

Hi all,

I have some logged data in a tab-separated .txt file with headers in first row, see attached file "torquedata.txt".

I have a short input script using textscan, which looks like this, called "read.m":

fid = fopen('torquedata.txt');
%data_text = textscan(fid, '%s %s %s %s %s %s', 1, 'Delimiter', '\t')
data = textscan(fid, '%f%f%f%f%f%f', 'Delimiter', '\t', 'headerlines', 1);
fclose(fid);

%

Can someone tell me why it only returns a 1x6cell "data" matrix with only the top left cell showing correct data?

>> run read >> data

data =

Columns 1 through 5

    [3.4455e+09]    [0x1 double]    [0x1 double]    [0x1 double]    [0x1 double]

Column 6

    [0x1 double]

Please assist, I would really appreciate it.
