[mirtoolbox] How can I get the attack times?

Hello,
I would like to extract the start points of attack intervals for further
processing. If I run "a = mironsets('music.wav','Attacks')", I see on
the figure the attack intervals. But if I want to save the data in a
text file, it becomes problematic. "mirgetdata(a)" gives me only the
onset times. I've tried also the following:
--------
a = mironsets('music.wav','Attacks');
o = mirgetdata(a);
% get the lengths of attack intervals at first
att_lengths = mirattacktime(a);
att_lengths_data = mirgetdata(att_lengths);
% calculate the starting points of attack intervals
attack_times = o - att_lengths_data;
--------
But here the subtraction doesn't work since the number of onset times is
not equal to the number of attack interval lengths!
Can you please give me a hint?
Thanks and best regards,
Igor
