Hi,

I'm trying to convert the aseg output of my longitudinal runs from FreeSurfer space back to native anatomical space by following the directions here:

https://surfer.nmr.mgh.harvard.edu/fswiki/FsAnat-to-NativeAnat

However, I've noted that none of my subjects have a <tpid>_to_<tpid>.long.<baseid>.lta transformation in <tpid>.long.<baseid>/mri/transforms. The transformations from each of the longs to the base (and vice-versa) are in the mri/transforms folder of the <templateid> directory, but that's about it, despite the fact that recon-all finished without errors. I'm using FreeSurfer v7.4.1.

Is this a feature of FreeSurfer v7 or is something going wrong somewhere?

Thanks in advance,

Christine
