hi

I found some issues using imread to read a multi-paged TIFF file.
The file under test can be downloaded from this link:

https://orbit.nmr.mgh.harvard.edu/plugins/scmsvn/viewcvs.php/*checkout*/trunk/iso2mesh/sample/headseg.tif?root=iso2mesh

when I use command

  brain=imread('headseg.tif',1:256);

I got an array of dimension 256x256x1x256
with all zeros elements.

If I used a loop, such as below, I can get 256x256x256 array,
but still all zeros.

  for i=1:256
     brain(:,:,i)=imread('headseg.tif',i);
  end

the above loop worked fine in Matlab.

is there a work-around to this?

thanks

Qianqian
