Hi,  
When I use mrview when displaying more than two different tck files, the overlapping part of the two fibre bundles appears white what is the reason for this?

Then my second question is how does my significance results file sig\_fixels\_05.mif file show up on the tck file on the glass brain, like the illustration.
