Hi Paul,
Thank you for the information regarding separate negative colour maps for voxels with negative values. I never thought of that.
However, that wasn't the issue with my colleague's statistical z-map of interest. The problem was that the entire background of the image consisted of nans. So, the solution was to remove all nans with the following fslmaths command:
fslmaths image -nan image_new
That fixed the problem. Nevertheless, thank you for your help!
Stefan
