Dear Miguel,
The variable in xY.y is the matrix of voxels values that should give you
what you want. Just type
>> xY.y
I hope this helps - Karl

Thanks for the 'spm_regions' function. However the function does
not save into a matrix the time courses for an activated cluster.
Instead provides the first eigenvector of a pre-specified region.
This is not exactly what I wanted. I wanted a matlab function
that provided matrices with the time courses (adjusted or not)
and, if possible, the voxel location.
Thanks
