[Freesurfer] Problems transforming T1 to talairach

2018-02-02 Thread Helen Beaumont
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?
