Dear Carles,
it's still not clear for me what you really intend. Do you need the voxel value at a specific coordinate or are you interested in getting the data voxel-by-voxel to use it for further analysis?
Anyway, if you are interested in the distribution of your values you can use cat_plot_histogram to compare the overall distribution between different maps.
This is a code snippet to read the values from a nifti file:
N = nifti(your_file);
dat = N.dat(:,:,:);
dat is a 3D matrix with the image valuies.
Best,
Christian
