Error: Index exceeds matrix dimensions.

obj=mmreader('ATMvid.avi');

a=read(obj, [10 200]);
%a=read(obj);
frames=get(obj,'numberOfFrames');% to find no.of frames
frames

for k = 1 : frames-1
source(k).cdata = a(:,:,:,k);
source(k).colormap = [];
end

In above code I am getting error "Index exceeds matrix dimensions.", please help

What you should do is

for k = 1 : size(a,4)
  source(k).cdata = a(:,:,:,k);
  source(k).colormap = [];
end

Error in ==> mmreader.mmreader at 66

uddobj = audiovideo.mmreader(fullFilePath);

code:

a=read(obj, [10 101]);
%a=read(obj);
frames=get(obj,'numberOfFrames');% to find no.of frames
frames

for k = 1 : size(a,4)
source(k).cdata = a(:,:,:,k);
source(k).colormap = [];
end

What does mmfileinfo say about the encoder?

Is it an Indeo5 file? And are you running on 64 bit Windows? If so then are you also running with 64 bit MATLAB ?

[pratibha rane]

yes, 64 bit windows 7.
