Hi,

I'm trying to set up a DTI-TK protocol where I register a Groupwise template to the ICBM- 152 standard space.
My groupwise template created by registering within subject templates which were created for each subject from each of the subjects two time points.
I've found that after the deformable alignment of the Group wise to the ICBM- 152 standard space the new GW to ICBM template looks very odd with no real definition of the brain structures.
It also leads to weird subject images when the are normalized to this template.
Is this normal or is there a way to correct for this?
Thanks
Lauren
