Dear Freesurfer experts,

 I just tried creating the -base for longitudinal processing on two time points using

recon-all -base <templateID> -tp <tp1id> -tp <tp2id> ... -all

After doing this, I received no error messages and a third folder named after the template name I had given
 it it was present in the subjects directory, however all of these files were empty. What have I done

 wrong?

Regards
