Hi FSLers,
My first pass with a group analysis was error free but the data I was using had yet to be
normalized. After normalizing datasets for a group analysis, I received the following message
listed below.
I believe the source of the problem to be that the 'mask voxel' total is set to 0 but not sure why
this is so. Also, I was able to run the same analysis when using data that was not yet normalized
without a problem - could this be the product of the altered values in the indiviual cope images?
Any advice?
Thanks!
Nicholas
