Dear Christian,
I am not sure whether I used your file correctly. When I ran your file, it asked
me to select a scan. Then should I select a series of segmentated images, or a
spmT.img?
I tried on a series of segmentated images (sn00.img), but then it produced a
series of li_sn00.img. Should I run those li_sn00.img in a model?
Since I thought Laterality Index means (contralateral voxel-ipsilateral
voxel)/(contralateral voxel+ipsilateral voxel). Therefore LI is a number from
-1.0 to 1.0. I am a bit confused of the proper use of your file.
Pls advice.
Many many thanks,
ANson
