Hi Maria
as long as the tal xform is reasonable I wouldn't worry about it, unless for some reason you care a lot about the accuracy of the talairach coords.
cheers Bruce
p.s. not sure why it would be smaller

Dear all,
sorry, if that question came up before in the mailing list and I simple have been unable to find the thread.
Following the wiki reconstruction workflow, I ran yesterday the recon-all -all process. The process finished without errors. So the next step was to check the talairach transform. Now, according to the FsTutorial/Talairach I have to make some adjustments and then run the whole process again. That is all nice and good.
However, why is it, that the talairach volume is always, no matter which subject I look at, is always significantly smaller than the target volume? Is that normal? Has it to be fixed? Or is that just normal? Attached find one example. As I am using freesurfer for the first time, I am really unsure about that.
Thanks for the help, Maria
