Hi Martin,

if you're using the Talairach transform to average data, then the most conservative thing to do would be to generate them all in the same way.

Hi, I'm doing a group study and I have a question regarding the Talairach transform. I need to make a new transform for some of my subjects using the brainmask.mgz-volume. For others, the original transform is okay (visually) . Is it a problem to have some transforms based on the brainmask volume, and others made from the nu volume? Should I make new transforms for all subjects, even though some of the original ones are fine?

Thanks,
