no, it's our own (.gca) template. It's the same type of linear registration that is used in the aseg, just this time to a template that has a skull in it On Tue, 19 Feb 2008, Doug Greve wrote:
Those are good questions. Bruce, does this use the mni305 template or a different one?

Hello,
In your experience, is the "talairach_with_skull.lta" transform always reasonable, or does it sometimes fail (and if the latter, is the failure rate dependent on the FS version, as is the case for talairach.xfm ?)
I ask because the ICV ("eTIV") value is derived from the determinant of "talairach_with_skull.lta". So, if we want to use the eTIV values as a covariate, should we be verifying the accuracy of this transform? And if so, what would the syntax be to do this in tkregister2 ?
