analyze75read and bad image quality

Hi, Im trying to open several images in Analyze 7.5 format taken from this site:

http://www.birncommunity.org/data-catalog/tet-off-amyloid-precursor-protein-app-transgenic-model/

but the results shown are not very good using the same code as the Matlab example (changing image name):

X = analyze75read('brainMRI');
X = flipdim(X,1);
Y = reshape(X(:,:,12:17),[size(X,1) size(X,2) 1 6]);
montage(Y);

The image shown is too dark but it´s good and detailed. But whe I try to open that different images, i can´t see any detail and the quality is poor. What should I do to see it correctly?

Perhaps montage is doing the equivalent of imagesc() ?

I don´t know. I am a beginner. The difference is that the MatLab image is uint8 and the others are double format. But I don´t know how to show them correctly.

Try

imagesc(Y(:,:,1))
