Ok, so I think the mwxi.nii should be it.

you are wellcome. I have never used that option, and I do not know how it works sorry. The mask needs to have a 0 for every voxel of the lesioned area and a 1 for every voxel outside the lesioned area. What I usually do is save the voi drowing as a nii file which gives you an image with 1 for voxels inside the lesion and 0 for voxels outside it. Then I use ImageCalc to do a 1 - i1.
Maybe there is a more direct and easy way to do this.

I changed the bounding box and it works - many thanks for your help! And you're right, of course, it's the Crinion-paper. And thanks for the other reference (Andersen et al 2010). As I am drawing lesion masks anyway (in MRIcron), I will give it a try. Do you know whether I just can use the "Create SPM5 masks" option in MRIcron for masking the lesion in SPM8? It creates two files (mwxi.nii and lwxi.nii), I guess I have to use mwxi.nii?
