I am using the command mri_convert -at transforms/talairach.xfm brain.mgz brain_in_tal.nii.gz
to convert a native-space skull-stripped T1 image to talairach space. I used recon-all to generate the transform matrix, and the segmentation and everything look good. But the T1_in_talairach image is not good - the brains are ending up different sizes, and frequently have the posterior chopped off. Please what am I doing wrong? Should I be applying the inverse of the transform?
