Hi Kate

the .lta format is for a linear registration (in ascii). YOu can just cat
it to see the contents - it is not a PET image (which will be stored in
.mgz or .nii). mri_convert or mri_vol2vol can be used to apply the
registration and/or change the output format (if you specify file.nii or
file.nii.gz it will write in Nifti)

cheers
Bruce
