Hello Igor,
Your strategy should work in principle. But there is a bug in version
1.1 of MIRtoolbox that induces this erroneous difference of size
between your two vectors. It should work better in version 1.2 that I
am preparing. There is a version apparently stable, that I can send
to any voluntary beta tester. The official release should come in 2
or 3 weeks, once I'll finnish with the documentation update.
Now there is a simple way to get the start points of attack intervals:
get(a,'AttackPosUnit')
I will add this in the documentation.
All the best,
Olivier

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
