I'm also puzzled about your "quantitative T1 maps". Are these T1 values

Hi Simon
what version are you using? Avi Snyder (ccd) has been tracking down some
interactions between his talairach code and our intensity normalization
that seem to have made it more fragilie, particularly in 5.1. He has some
suggested fixes that may improve things for you.

Hello,
since I experienced a high rate of registration errors using talairach_avi in
the conventional recon-all processing stream (more than 50% misregistration), I
would like to incorporate SPM affine registration parameters (as provided in
the seg_inv_sn.mat file obtained from the segmentatio
